Find the volume of a rectangular prism with base length = 8 ft base width=5ft and height = 2 ft

80 ft^3

Step-by-step explanation:

(Base*Length)*Height=Volume

(8*5)=(40)

40*2=80

80

Step-by-step explanation:

The volume of a rectangular prism can be solved by V = w*h*l

In this case...

w=5ft

h=2ft

l=8ft

So 5 * 2 * 8 = 80 ft^3

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
