✏️VOLUME
Solution:
Figure #1.
Since the given is a rectangular prism, use the formula:
Where:
- l - length
- w - width
- h - height
Given:
- l = 15 in.
- w = 6 in.
- h = 8 in.
» Substitute the givens on the formula.
- V = lwh
- V = (15 in.)(6 in.)(8 in.)
- V = (90 in.²)(18 in.)
- V = 1 620 in.³
Therefore, the volume of the rectangular prism is 1 620 in.³
Figure #2
Since the given a cube, use the formula:
Where:
Given:
» Substitute the given on the formula.
- e³
- (9 in.)³
- (9 in.)(9 in.)(9 in.)
- 729 in.³
Therefore, the volume of the cube is 729 in.³
Figure #3
Since the given is a cylinder, use the formula:
Where:
- π - pi (3.14)
- r - radius
- h - height
Given:
» Substitute the givens on the formula.
- V = πr²h
- V = (3.14)(8 in.)(14 in.)
- V = (25.12 in.)(14 in.)
- V = 351.68 in.³
Therefore, the volume of the cylinder is 351.68 in.³
