Question

Find the surface area of the prism.

Answer 1

Answer:

The surface area of the prism is 386m²

Step-by-step explanation:

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

$2 \times (lenght) \times (widht) + 2 \times (lenght) \times (height) + 2 \times (width) \times (height)$

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

$2 \times 15 \times 7 + 2 \times 15 \times 4 + 2 \times 7 \times 4$

Simplify each term.

$210 + 120 + 56$

Simplify by adding numbers.

$386m ^{2}$

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