Problems & Solutions

Veronica bought a tent for her camping trip this weekend. The shape of the tent is a right triangular

prism lying on its side, as shown. (The front and back sides of the tent, which are the prisms bases, are

isosceles triangles.) If the height of the tent is 6 feet at the tallest point, the front base of the tent is 5

The volume of a right triangular prism can be found using the formula V = B × h, where B = the area of

the base and h = the height of the prism. So, given the measurements above, we can calculate the volume to be V = B × h = (1/2)(5)(6) × 7 = 105 cubic feet. covers all of the sides of the tent (except the bottom) perfectly, how many square feet is the fly?

The front and back of the tent each have an area of (1/2)(5)(6) = 15 square feet. Now, to figure out the

area of the two slanted sides of the tent, we must determine the slant height of the tent. By drawing in

the height of the front of the tent, we get two right triangles, so we can use the Pythagorean Theorem to

of the tent has an area of 7 × (13/2) = 91/2 square feet. Therefore, since the fly covers the sides of the

tent perfectly, the fly must be (15)(2) + (91/2)(2) = 30 + 91 = 121 square feet.

Veronica plans to put an air mattress under her sleeping bag for extra cushion. When the mattress is full

of air, it is 4 inches thick, contains 6 cubic feet of air and forms a right rectangular prism. When lying flat

on the ground parallel to the position of the tent floor, the mattress fits completely inside of the tent. If

the length and width are each an integer number of feet, what are the dimensions of the base of the mattress?

Since the volume of a rectangular prism is length × width × height, we can say that 6 = l × w × (1/3), since

4 inches is the same as 1/3 of a foot. This tells us that l × w = 18 square inches. If the length and width

are both integers and it must fit within the 5 feet by 7 feet base of the tent, the dimensions of the base of

the mattress must be 6 feet by 3 feet.
