Question

The net below has dimensions l = 14 feet, w = 7 feet, and h = 13 feet. How will the surface area of the figure change if the width decreases by 2 feet?

Answer 1

856 should be the answer

Answer 2

Explanation:

So, we know that the width in this image has a length of 7 feet. decreasing it by two will give us 5 feet. Now, we can solve the surface area.

Lateral faces: 7 x 14 x 4 = 392

Bases: 14 x 13 x 2 = 364

Add them all up, and we get 756 ft²
