Surface area of Rectangular Prisms practice.

Question

question 1 of 5
what is the surface area of the rectangular prism?

Answer 1

To find the surface area of a rectangular prism, you would first calculate the area of each of the six sides and then add them together.

Let's say the dimensions of the rectangular prism are:
Length = 5 units
Width = 3 units
Height = 4 units

To find the surface area, you would calculate the area of each side:
1. Top and bottom faces:
Area = Length * Width = 5 units * 3 units = 15 square units (each)
Total top and bottom area = 2 * 15 = 30 square units

2. Front and back faces:
Area = Length * Height = 5 units * 4 units = 20 square units (each)
Total front and back area = 2 * 20 = 40 square units

3. Left and right side faces:
Area = Width * Height = 3 units * 4 units = 12 square units (each)
Total left and right side area = 2 * 12 = 24 square units

Now, add the areas of all six sides to find the total surface area:
Total surface area = 30 + 40 + 24 = 94 square units

So, the surface area of the rectangular prism is 94 square units.
