Question

bill knows that the volume of a rectangular prism is 400cm3. The box is labelled with the length as 6.5cm and the width as 1.5cm. What is the approximate height of the box?

Answer 1

The volume = length X width X height
Putting known values

400 = 6.5 X 1.5 X Height
400 = 9.75 X Height
Dividing both sides by 9.75, we get

Height = 41.024 cm

Answer 2

(400/6.5)/1.5= approx. 41cm tall
divide the total volume by the other known dimensions to get the height
