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.
