The volume of a rectangular prism is the length multiplied by the width and height. You may not have multiplied correctly or multiplied all of the dimensions.
So, let's multiply our dimensions, 4cm × 6cm × 5 cm.
4 · 6 · 5 = 120
4 times 6 equals 24, then 24 times 5 is 120.
The volume of the box, then, is 120cm³. Remember to use the ³ (cubed) sign for volume.
