VOLUME OF RECTANGULAR PRISMS WORKSHEET

Find the volume of the rectangular prism :

Question 1 :

Question 2 :

Question 3 :

1. Answer :

We can find volume of the rectangular prism (cuboid) using the formula given below.

Base area x Height

Here, the base is a rectangle with length 12 cm and width 4 cm.

Area of the base is

= 12 x 4

= 48 cm²

Height of the cuboid is 8 cm.

So, volume of the above cuboid is

= 48 x 8

= 384 cm³

2. Answer :

We can find volume of the rectangular prism using the formula given below.

Base area x Height

Here, the base is a rectangle with length 3 m and width 2 1/4 m.

Area of the base is

= 3 x 2 1/4

= 3 x 9/4

= 27/4 m²

Height of the rectangular prism is 4 1/2 m.

So, volume of the above rectangular prism is

= 4 1/2  x 27/4

= (9/2)  x (27/4)

= 243/8

= 30 3/8 m³

3. Answer :

We can find volume of the rectangular prism using the formula given below.

Base area x Height

Here, the base is a rectangle with length 7 1/2 inches and width 4 inches.

Area of the base is

= 7 1/2 x 4

= (15/2) x 4

= 30 in²

Height of the rectangular prism is 2 1/2 inches.

So, volume of the above rectangular prism is 

= 30 x 2 1/2

= 30  x 5/2

= 150/2

= 75 in³
