Arectangle pyramid has a volume of 160 cubic feet. find two possible sets of measurements for the base area and height of the pyramid?

where  is the area .
Set this to 160 and multiply by three:

Now, think of two numbers that multiply together to make 480. One possible solution could be that the base area is 12 square feet, and the height is 40 feet.
Or you could have the base as 1 square foot, and the height as a whopping 480 feet (which wouldn't make for a good pyramid at all)!

Two solutions I would use:
1:   base area 12 square feet, height 40 feet.
2:   base area 24 square feet, height 20 feet.

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
