volume of cube l×b×h

mark me as brain list and please follow me

Answer 2

The area of a circle is π r². r is the radius. Radius is the half of a diameter and π=22/7 that is 3.14 . Just multiply radius 2 times.For example:

radius= 2 cm, π= 3.14 or 22/7. Then, r²=2²=2×2=4cm².

Therefore, area of circle= 22/7×4=3.14×4=12.56 cm²

The formula for volume of a cube is a³, where a is the measure of side of a cube. You have to just multiply the side 3 times. For example:

side of cube= 2 cm. Then volume=2³=2×2×2=8cm³
