# Question #048ff

##### 1 Answer

Hence, theWhole surface area is

Volume = Area of the base x height

#### Explanation:

1)

The base can be considered a a combination of

A square of side 10 cm

A triangle with base as 6 cm and altitude as 8 cm.

Thus, the area of the top face = area of bottom face =

Area of top face

Area of bottom face

Perimeter = 10+10+10+6+8=30+14=44cm

Area of the lateral surface=Perimeter x Height

Area of the lateral surface

Hence, the total area is

Volume = Area of the base x height
