### Rectangular Prism Calculator :

This rectangular prism calculator will help you to work out the volume, surface area, and diagonal of that solid and you get the calculation below the calculator.

### 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
