Answer 1

S = 40 square inches

Explanation:

Surface area = area of base + area of lateral faces

Area of the base (square):

A = lw

A = 4(4)

A = 16

Area of lateral faces (triangle and there are 4 of them):

A = bh/2

A = 3(4)/2

A = 12/2

A = 6

Since there are 4 lateral faces, multiply the area by 4.

6 x 4 = 24

Surface area = 16 + 24

S = 40 square inches
