The image above is a rectangular prism. To calculate the volume of a rectangular prism requires three essential parameters which are the length, width and height of the rectangular prism.
V = lwh
Where;
V = Volume of the rectangular prism
l = Length of the rectangular prism
w = Width of the rectangular prism
h = Height of the rectangular prism
Let’s solve an example;
Find the volume of a rectangular prism with a length of 18 cm, a width of 12 cm and a height of 21 cm.
This implies that;
l = Length of the rectangular prism = 18 cm
w = Width of the rectangular prism = 12 cm
h = Height of the rectangular prism = 21 cm
That is, V = lwh
V = 18 x 12 x 21
V = 4536
Therefore, the volume of the rectangular prism is 4536 cm3.
Calculating the Length of a Rectangular Prism using the Volume, Width and Height of the Rectangular Prism
l = V / wh
Where;
l = Length of the rectangular prism
V = Volume of the rectangular prism
w = Width of the rectangular prism
h = Height of the rectangular prism
Let’s solve an example;
Find the length of a rectangular prism with a width of 19 cm, a height of 24 cm and a Volume of 250 cm3.
This implies that;
w = Width of the rectangular prism = 19 cm
h = Height of the rectangular prism = 24 cm
V = Volume of the rectangular prism =Â 250 cm3
l = V / wh
l = 250 / 19 x 24
That is, l = 250 / 456
l = 0.55
Therefore, the length of the rectangular prism is 0.55 cm.

Calculating the Width of the Rectangular Prism using the Height, the Volume and the Length of the Rectangular Prism
w = V / lh
Where;
w = Width of the rectangular prism
V = Volume of the rectangular prism
l = Length of the rectangular prism
h = height of the rectangular prism
Let’s solve an example;
Given that the height of a rectangular prism is 30 cm, the Volume is 320 cm3 and the length is 15 cm. Find the width of the rectangular prism?
This implies that;
h = Height of the rectangular prism = 30 cm
V = Volume of the rectangular prism = 320Â cm3
l = Length of the rectangular prism = 15 cm
w = V / lh
w = 320 / 15 x 30
So, w = 320 / 450
w = 0.71
Therefore, the width of the rectangular prism is 0.71 cm.
Calculating the Height of the Rectangular Prism using the Width, the Volume and the Length of the Rectangular Prism
h = V / lw
Where;
w = Width of the rectangular prism
V = Volume of the rectangular prism
l = Length of the rectangular prism
h = height of the rectangular prism
Let’s solve an example;
Given that the width of a rectangular prism is 25 cm, the Volume is 220 cm3 and the length is 19 cm. Find the height of the rectangular prism?
This implies that;
w = Width of the rectangular prism = 25 cm
V = Volume of the rectangular prism = 220Â cm3
l = Length of the rectangular prism = 19 cm
h = V / lw
h = 220 / 19 x 25
Then, h = 220 / 475
h = 0.46
Therefore, the height of the rectangular prism is 0.46 cm.
