Apyramid with a rectangular base has a volume of 480 cubic inches and a height of 10 inches. the width of the rectangular base is 9 inches. find the length of the rectangular base.

We have the formula of the volume: 480 = area rectangular base x 10 / 3 ;

Then, 480 x 3 = area reactangular base x 10;

Area rectangular base = 480 x 3 / 10;

10 x ( 9 x length ) = 480 x 3;

90 x width = 1440;

length = 1440/90;

length = 16 inches;

28

step-by-step explanation:

8+8+6+6

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
