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?

42.06 ft²

Step-by-step 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
