Question

how many square inches of wrapping paper are needed to wrap a present that is 12 inches wide, 5 inches deep and 12 inches tall

Answer 1

ok

Area of a rectangular prism: 2(wide x deep) + 2(wide x tall) + 2(tall x deep)

Substitution

Area = 2(12 x 5) + 2(12 x 12) + 2(5 x 12)

Simplification

Area = 2(60) + 2(144) + 2(60)

Area = 120 + 288 + 120

Result

Area = 528 in^2
