A tissue box has a volume of 105 cm³. If the length of the box is 7 cm and the width is 5 cm, what is the surface area of the box? *

142 cm²
35 cm²
735 cm²
365 cm²

FInd the height of the box by dividing the volume by 7 x 5 ( length x width)

Height = 105 / 35

Height = 3cm

There are 6 sides to a box.

Surface area = 2 x length x width + 2 x length x height + 2 times height x width

SA = 2*7*5 + 2*7*3 + 2*5*3

SA = 70 + 42 + 30

SA = 142 cm^2
