### Prism Formula :

Prism formula of surface area of a prism_{(cm)} in centimeter is equal to the two and multiply the Base area _{(cm)} in centimeter and addition the lateral surface area_{(cm)} in centimeter of the prism. Hence the prism formula can be written as,

**Surface area of a prism _{(cm)} =2* Base area_{(cm)}+lateral surface area_{(cm)}**

**Volume=Base area * Height**

### Example :1

Calculate the Base area is 8cm and lateral surface area 20cm and find the surface area of prism?

### Answer:

Base area =8cm

Surface area=20cm

Using the formula

Surface area of a prism_{(cm)}=2* Base area_{(cm)}+lateral surface area_{(cm)}

=2*8+20=36cm

### Example:2

Calculate the Base area is 16cm and lateral surface area 30cm and find the surface area of prism?

### Answer:

Base area =16cm

Surface area=30cm

Using the formula

Surface area of a prism_{(cm)}=2* Base area_{(cm)}+lateral surface area_{(cm)}

=2*16+30=62cm
