Question

What is the surface area of a box with a length of 6 ft, a width of 3 ft, and a height of 2½ ft?

Answer 1

Explanation:

Remark

The surface area is the area of all six sides when the object is a box.

Formula

SA = 2*L*w + 2*L*h + 2*w*h

Givens

L = 6 ft

w= 3 ft

h = 2.5 feet

Substitute and Solution

SA = 2*6*3 + 2*6*2.5 + 2*3*2.5

SA = 36 + 30 + 15

SA = 81
