Answer 5

do you know how to find the area of a rectangle?

Answer 6

area=wh

Answer 7

correct, a box is just alot of rectangles stacked on top of each other.

length, times width, times height

the give you the bottom of the box as 12 x 12, and the height of the box as 7.8

so, to start with we would want to know the volume of that box before we can determine the pyrimad inside of it

Answer 8

isn't it 1/3 (area of base)(height)

Answer 9

yes, area of the base is 12 x 12, the height is 7.8

then we would want to divide that by 3 to get the pyramid itself

Answer 10

144 * 7.8 = 1123.3 divided by 3 = 374.4 is that right
