From the picture, we know the dimensions of the mattress, which is a prism. The exercise is to find the width w of the prism. Let's see the diagram!
Now we can see that the prism has the length l of 19 inches and the height h of 1 34 inches. The volume V of the prism is 532 cubic inches. The volume of a rectangular prism with length l, width w, and height h can be calculated using the following formula.
V=l wh
We can substitute the known values into this formula and solve for the width w. Let's do it!
