Question

You can use a calculator for this question. Greg builds a new pond which has a volume of 7.35 m3. It is 4.2 m long and 50 cm deep. What is the width of the pond? m

Answer 1

The formula of getting the volume of a regular prism is L x W x H = V.
Given: V: 7.35m3
           L:  4.2 m
           H: 50 cm (Convert this to meters) = 0.5m
           W: ?
L x W x H = V
4.2 x W x 0.5m = 7.35m3
2.1m2 x W = 7.35m3 <-- Divide both sides by 2.1m2
The result would be W= 3.5m
So the width of the pond is 3.5m
Hope this solution helps you!
