Find the surface area of the exhibit of a figure with 7 length 4 width and 19 hight

Answer 1

To find the surface area of an exhibit with length 7, width 4, and height 19, we need to calculate the area of each face and then add them together.

1. The area of the top face is the length multiplied by the width: 7 * 4 = 28 square units.
2. The area of the bottom face is also 28 square units.
3. The area of the front and back faces can be calculated by multiplying the height by the width: 19 * 4 = 76 square units each.
4. The area of the left and right faces can be calculated by multiplying the height by the length: 19 * 7 = 133 square units each.

Adding up all the areas:
28 + 28 + 76 + 76 + 133 + 133 = 474 square units.

Therefore, the surface area of the exhibit is 474 square units.
