Some students were measuring the volume of a cube shaped wooden block. They measured the length to be 5.08 cm, the width to be 5.09 cm, and the height to be 5.10 cm. The actual volume of the block was 15.3 cm3. What was their percent error

762%

Step-by-step explanation:

Volume of a cube = s³

Volume of the cube is then

V = 5.08 * 5.09 * 5.1

V = 131.87 cm³

Percentage errors are calculated by the formula

%E = (V.a - V.e)/V.e * 100%, where

%E = percentage error

V.a = actual volume

V.e = expected volume

%E = (131.87 - 15.3) / 15.3 * 100%

%E = 116.57 / 15.3 * 100%

%E = 7.62 * 100%

%E = 762%

Therefore, the percentage error is a whooping 762% which is a whole lot!
