Rectangular Prism Formula :

The Rectangular prism of the volume(cm) in centimeter is equal to the product of length l(cm) in centimeter and multiply the width w(cm) in centimeter and multiply the height h(cm) in centimeter .Hence the rectangular prism can be written as

The volume of a rectangular prism=Length*width*height cubic units

Volume =l(cm)*w(cm)*h(cm) cubic units

Lateral surface area =p*h[square units]

P → perimeter of a base

H → height of the prism

The perimeter of the rectangular prism is

P=2(l+w)

The lateral surface area (LSA) of a rectangular prism =2*(l+w)h square units

TSA=LSA+2(Base Area)=2(l+w)h+2(l*w)=2lh+2wh+2lw[square units]

Surface Area of a rectangular prism=2(lh+wh+lw) square units

Problem:1

Calculate the volume of a rectangular prism whose length, width and length are 9cm,6cm, and 3cm respectively ?

Answer:

Given,

Length l=9cm

Width w=6cm

Height h=3cm

The formula to find the volume of a rectangular prism is

V=length*width*height cubic units

V=9*6*3 cm3

V=162cm3

Therefore the volume of a rectangular prism is 162 cm3

Problem :2

Calculate the surface area of a rectangular prism whose length, width, and height are 8cm,4cm, 5cm respectively?

Answer:

Length l=8cm

Width w=4cm

Height h=5cm

The formula to find the area of rectangular prism is

A=2(l*h+w*h+l*w)

A=2(8*5+4*5+8*4)

A=2(100)

A=200 sq cm
