A rectangular prism has a length of 7 m, a height of 5 m, and a volume of 140 m3. What is the width?
A prism has a length of 7 meters, width of w, and height of 5 meters.
Which steps are correct? Check all that apply.
Substitute the known values into the formula:
140 = 7(w)(5).
Substitute the known values into the formula:
7 = 140(w)(5).
Substitute the known values into the formula:
5 = 7(w)(140).
Solve for the unknown: w = 4 m.
Solve for the unknown: w = 7 m.
Solve for the unknown: w = 2 m.
140 = 7(w)(5).
The correct steps to find the width of the rectangular prism are:
1. Substitute the known values into the formula: 140 = 7(w)(5).
2. Solve for the unknown: w = 140 / (7 * 5). Simplifying gives w = 4 m.
So, the correct steps are:
- Substitute the known values into the formula: 140 = 7(w)(5).
- Solve for the unknown: w = 4 m.
The steps "Substitute the known values into the formula: 7 = 140(w)(5)." and "Substitute the known values into the formula: 5 = 7(w)(140)." are incorrect as they have the known values in the wrong places.
