Question

Antoine is wrapping a block of cheese that is 22 centimeters long by 6 centimeters high by 10 centimeters wide with plastic wrap. What is the surface area of the cheese box?

Answer 1

The answer would be 824 sq. Centimeters

Answer 2

length = 22 cm
width = 10 cm
height = 6 cm

Surface area of a rectangular prism (cheese box) = 2B + PH
Word form ⇒ 2(Area of base) + (perimeter of base)(height)

Find the measurements needed for the formula.
Area of base = 22 × 10 = 220 cm²

Perimeter of base = 22 + 10 + 22 + 10 = 64 cm

Height = 22 cm

Plug these into the formula.
2(220) + (64)(22) = 1,848

The SA of the cheese box is 1,848 cm².
