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?

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
