To find the surface area of an object, you will need to calculate the total area of all its surfaces combined. The formula you use will depend on the shape of the object. Below are some common shapes and their respective surface area formulas:
1. Cube:
Surface area = 6 x (side length)^2
2. Rectangular prism:
Surface area = 2lw + 2lh + 2wh
where l = length, w = width, h = height
3. Cylinder:
Surface area = 2πr^2 + 2πrh
where r = radius, h = height
4. Sphere:
Surface area = 4πr^2
where r = radius
5. Cone:
Surface area = πr^2 + πr√(r^2 + h^2)
where r = radius, h = height
You can use these formulas to calculate the surface area of the object you want to find the surface area of. Simply plug in the dimensions of the object into the appropriate formula and solve for the surface area.

If you are trying to find the surface area of a flat two-dimensional object, such as a rectangle or square, then yes, you can find the surface area by multiplying the length and width of the object.
For example, the surface area of a rectangle is equal to the length multiplied by the width:
Surface area = length x width
For a square, where all sides are equal:
Surface area = side length x side length or Surface area = side length^2
Keep in mind that this method only applies to flat objects with two dimensions. For three-dimensional objects, you will need to use the appropriate formula for its shape to find the surface area.

To find the surface area of a rectangular prism with length 5 inches, width 4 inches, and height 3 inches, you can use the formula:
Surface area = 2lw + 2lh + 2wh
Substitute the values:
Surface area = 2(5)(4) + 2(5)(3) + 2(4)(3)
Surface area = 40 + 30 + 24
Surface area = 94 square inches
Therefore, the surface area of a rectangular prism with a height of 3 inches, length of 5 inches, and width of 4 inches is 94 square inches.
Surface area = 2lw + 2lh + 2wh
Substitute the values:
Surface area = 2(5)(4) + 2(5)(3) + 2(4)(3)
Surface area = 40 + 30 + 24
Surface area = 94 square inches
Therefore, the surface area of a rectangular prism with a height of 3 inches, length of 5 inches, and width of 4 inches is 94 square inches.

Sure! Let's break it down into simpler terms.
To find the surface area of an object, think of it like wrapping a present. You're trying to find out how much wrapping paper you would need to cover all the sides of the object.
For a rectangular prism (which is like a box shape), you can imagine it as having 6 faces total. The surface area is how much area all of these faces add up to.
To find the surface area of a rectangular prism, you need to add up the areas of all its faces. The formula to find the surface area of a rectangular prism is:
Surface area = 2lw + 2lh + 2wh
Here's what each part of the formula means:
- l represents the length of the prism
- w represents the width of the prism
- h represents the height of the prism
So, to find the surface area of a rectangular prism with a length of 5 inches, a width of 4 inches, and a height of 3 inches, you'd plug in these values into the formula:
Surface area = 2(5)(4) + 2(5)(3) + 2(4)(3)
Surface area = 40 + 30 + 24
Surface area = 94 square inches
That's how you find the surface area of a rectangular prism!

Answer
is 2lw 2 x length x width + 2lh 2 x length x height

Yes, that's correct! In the formula for finding the surface area of a rectangular prism, 2lw represents 2 times the length times the width, and 2lh represents 2 times the length times the height.
So, if you have the length (l), width (w), and height (h) of the rectangular prism, you would calculate these two terms by multiplying the corresponding dimensions and then adding them all together with the third term 2wh (2 times the width times the height) to find the total surface area.
