What is the volume in cubic meters of cement needed for a walkway that is 7 m long, 0.95 m wide, and 10 cm deep?

What is the volume in cubic meters of cement needed for a walkway that is 7 m long, 0.95 m wide, and 10 cm deep?

• A. 0.0665 m3
• B. 0.095 m3
• C. 0.105 m3
• D. 0.065 m3

Answer: (A)

To determine the volume of cement needed for the walkway, it's important to use the formula for calculating volume, which is length × width × depth. In this case, the dimensions provided are: - Length: 7 meters - Width: 0.95 meters - Depth: 10 cm (which needs to be converted to meters, so 10 cm equals 0.1 meters). Now, substituting these values into the volume formula gives: \[ \text{Volume} = \text{Length} \times \text{Width} \times \text{Depth} \] \[ \text{Volume} = 7 \, \text{m} \times 0.95 \, \text{m} \times 0.1 \, \text{m} \] Calculating this: \[ \text{Volume} = 7 \times 0.95 \times 0.1 = 0.0665 \, \text{m}^3 \] This calculation shows that the correct volume of cement needed for the walkway is indeed 0.0665 cubic meters. This corresponds to the first choice, indicating a proper understanding of how to convert units and apply the volume formula

To determine the volume of cement needed for the walkway, it's important to use the formula for calculating volume, which is length × width × depth. In this case, the dimensions provided are:

• Length: 7 meters

• Width: 0.95 meters

• Depth: 10 cm (which needs to be converted to meters, so 10 cm equals 0.1 meters).

Now, substituting these values into the volume formula gives:

[ \text{Volume} = \text{Length} \times \text{Width} \times \text{Depth} ]

[ \text{Volume} = 7 , \text{m} \times 0.95 , \text{m} \times 0.1 , \text{m} ]

Calculating this:

[ \text{Volume} = 7 \times 0.95 \times 0.1 = 0.0665 , \text{m}^3 ]

This calculation shows that the correct volume of cement needed for the walkway is indeed 0.0665 cubic meters. This corresponds to the first choice, indicating a proper understanding of how to convert units and apply the volume formula
