Rectangular Prism Formula :

Rectangular prism formula base area(cm) in centimeter is equal to the base length b(cm) and multiply the base width length l(cm) in centimeter .Hence the Rectangular prism formula can be written as,

Base Area(cm)=b(cm)*l(cm)

Surface area=2*(bl+lh+bh)

Volume =l*w*h

B→ base length in cm

L→ base width in cm

H→ height in cm

Sample sums :

Sum 1:

Calculate the surface area of a rectangular prism whose length, base, and height are 4cm, 8cm and 15cm respectively?

Answer:

Given,

Length l=4cm

base=8cm

Height h=15cm

The formula to find the area of a rectangular prism is

A=2*(bl+lh+bh)

A=2(8*4+4*15+8*15)

A=2*212

A=424 sq.cm

Sum 2:

Calculate the surface area of a rectangular prism whose length, base, and height are 20cm, 30cm and 40cm respectively?

Answer:

Given,

Length l=20cm

base=30cm

Height h=40cm

The formula to find the area of a rectangular prism is

A=2*(bl+lh+bh)

A=2(30*20+20*40+30*40)

A=2*2600

A=5200sq.cm
