V = WLH
V = πR^{2}H
Width (W) | = 20mm |
Length (L) | = 5cm |
Height (H) | = 3cm |
Width (W) | = 2cm |
Length (L) | = 5cm |
Height (H) | = 3cm |
V = WLHNotice the cm^{3} (cubic centimeter) above? This 'cubic' comes about because we multiplied 3 lengths that are in cm. If W, L and H are in feet (ft), the unit for volume will be ft^{3} (cubic feet). Generally speaking, unit^{3} is the unit for volume where the unit can be mm, cm, m, feet, km, miles etc.
= 2×5×3
= 30 cm^{3}
