Question

A rectangular prism has a length of 10 cm and width of 5 cm. If the volume of the prism is 250 cm3 , find the height. (Volume of a rectangular prism is V = LWH)

Answer 1

Answer:

The height is 5.

Step-by-step explanation:

Volume = L x W x H

L= 10

W= 5

H= ?

10 x 5 x ?

10 x 5 = 50

50 x ? = 250

We know 50 x 2 = 100

So 50 x 4 = 200

So 50 x 5 will = 250

10 x 5 x 5

10 x 5 = 50

50 x 5 = 250

Rearranging to check work

5 x 5 x 10

5 x 5 = 25

25 x 10 = 250

I was right

Hope this answers your question.

Answer 2

Height = 5cm

This is because

L=10

W=5

10 x 5 = 50

50 x ? = 250

---- ------

50 50

? = 5

The height is 5
