Volume Word Problems
1. The volume of the cylindrical pencil
holder is 602.88 cm³. 2. The spherical tank can hold 904.32 cubic meters of water.
Volume refers to the three-dimensional space enclosed by a boundary or occupied by an object. The volume of an object determines the amount required to fill that object. It can be measured in cubic units.
Solution:
1. The problem is asking for the volume of the cylindrical pencil holder. To find the answer, use the formula in finding the volume of a cylinder which is V = nr²h. Since the diameter is given which is 8 cm, get the half of it as the radius.
V = πr²h
= (3.14) (4 cm)² (12 cm) = (3.14) (16 cm²) (12 cm)
= 602.88 cm³
2. The problem is asking for amount of water that the spherical tank can hold. To find the answer, use the formula in finding the volume of a sphere. It is V = 4/3Tr³.
V = 4/3TTr³
= 4/3 (3.14) (6 m)³
= 4/3 (3.14) (216 m³)
= 4/3 (678.24 m³)
= 904.32 m³
