Answer 1

Question 1:

For this case we have that by definition, the volume of a prism is given by:

`V = a * b * c`

Where:

a: It is the long

b: It is the width

c: It is the height

According to the data we have:

`a = 18m\\b = 9m\\c = 6m`

Substituting:

`V = 18 * 9 * 6\\V = 972`

Thus, the volume of the building is
`972 \m ^ 3`

Answer:

Option B

Question 2:

For this case we have that by definition, the volume of a prism is given by:

`V = a * b * c`

Where:

a: It's the long

b: It is the width

c: It is the height

According to the data we have:

`a = 26in\\b = 14in\\c = 18in`

Substituting:

`V = 26 * 14 * 18\\V = 6552`

Thus, the volume of the tank is
`6552 \in ^ 3`

Answer:

Option A

Question 3:

For this case we have that by definition, the volume of a cube is given by:

`V = l ^ 3`

Where:

l: It's the side of the cube

According to the data we have that the cube side is 7.2ft.

Substituting we have:

`V = (7.2) ^ 3\\V = 373.25`

Rounding off we have that the volume of the cube is
`373.25 \ ft ^ 3`

Answer:

Option B

Question 4:

For this case we have that by definition, the volume of a cube is given by the following formula:

`V = l ^ 3`

Where:

l: It's the side of the cube

According to the data we have that the cube side is 4.5 yards.

Substituting we have:

`V = (4.5) ^ 3\\V = 91.125`

Rounding off we have the cube volume is
`91.13 \ yd ^ 3`

Answer:

Option C
