Question

Justin wanted to wrap his moms birthday present shaped like a rectangular prism with pretty paper. The box is 2.1 feet long, 2.7 feet wide, And 3.2 feet high. What is the total surface area of the box?

Answer 1

42.06 ft²

Explanation:

2 sides = 2(2.7 ft × 3.2 ft) = 2 × 8.64 ft² = 17.28 ft²

Front + back = 2(2.1 ft × 3.2 ft) = 2 × 6.72 ft² = 13.44 ft²

Top + bottom = 2(2.1 ft × 2.7 ft) = 2 × 5.67 ft² = 11.34 ft²

Total area = 42.06 ft²
