Question

The volume of a cube is 3944.312 cm³. Find the length of a side. round your answer to the nearest 10th and write only the measurement

15.8

62.8

36.3

21.7

Answer 1

volume is a cubic measurement of the length×width×height, and as the shape is a cube, then its height, width and length are equal. This means that the length of a side is cubed to get the volume, as all the side are the same length. So to find out the length of a side, do

`\sqrt[3]{3944.312} = 15.8`
To the nearest 10th, 15.8 is 20 as you round units from 5-9 upwards
