11.) The volume of the given cube would be = 216m³.
13) The Volume of a cone = 8,273.3in³
How to calculate the volume of the given figure?
To calculate the volume of the given figure, the following steps should be taken as follows:
For question 11.)
The formula for volume of cube = a³
Where a = 6m
Volume = 6³ = 216m³.
For question 13.)
The formula for volume of a cone;
= ⅓πr²h
r = 20
h = 20
volume = ⅓×(3.14)(20)²×20
= 25120/3
