Question

Find the surface area of the prism.

Answer 1

The surface area of the prism is 386m²

Explanation:

The surface area of a box is equal to the sum of the areas of each side of the box.

`2 * (lenght) * (widht) + 2 * (lenght) * (height) + 2 * (width) * (height)`

Substitute the values of the length l=15, the width w=7, and the height h=4 into the formula.

`2 * 15 * 7 + 2 * 15 * 4 + 2 * 7 * 4`

Simplify each term.

`210 + 120 + 56`

Simplify by adding numbers.

`386m ^(2)`

Hence, the Surface area of this prism is 386m².
