A rectangular prism has a length of 12 cm and a width of 4 cm. If the volume of the prism is 240 cm3, what is the height?

Question

anonymous · Answer

240/(12 * 4) = 5cm

anonymous · Answer

Thats wrong, the volume is got by first finding the area of the triangle and then multiplying by the width.

anonymous · Answer

The volume of a rectangular prism can be found by the formula:
volume=length*width*height

240 = 12 * 4 * height
height = 240 /(12 * 4) = 5cm
