4. A rectangular prism has a length that is twice the width and a height that is 5 times the width. [5marks] Give an expression for the volume of the prism. Find the dimensions when the prism has a volume of 1400 cubic inches.
Added by Mariano M.
Step 1
Let the width be represented by \( w \). According to the problem, the length \( l \) is twice the width, so we can express it as: \[ l = 2w \] The height \( h \) is five times the width, so we can express it as: \[ h = 5w \] Show more…

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 = 7w(5). Substitute the known values into the formula: 7 = 140w(5). Substitute the known values into the formula: 5 = 7w(140). Solve for the unknown: w = 4 m. Solve for the unknown: w = 7 m. Solve for the unknown: w = 2 m.

A small rectangular prism has a length of 6 1/2 inches, a width of 4 inches, and a volume of 117 cubic inches. A large rectangular prism also has a length of 6 1/2 inches and a width of 4 inches, but its volume is 175 1/2 cubic inches. How much taller is the large prism than the small prism?
