Question

This the top view of an area ABCD to be concreted. The area is to be first framed by wood. It will be filled with concrete to a depth of 10 cm. The area of the shape is 11 square meters. how much of concrete filling is required.

Answer 1

1.1 cubic meters of concrete is required

Explanation:

The area = l*b = 11 sq. m.

The depth d = 10 cm

1 cm = 0.01 m

⇒ 10 cm = 10*0.01 m

⇒ 10 cm = 0.1 m

⇒ d = 0.1 m

The volume = l*b*d

= 11 * 0.1

= 1.1

1.1 cubic meters of concrete is required
