The volume of a cylinder is 81 ft3. The volume of a cube is 42 ft3. What is the difference between the volume of a cone that fits exactly inside the cylinder and the volume of a pyramid that fits exactly inside the cube?

do you know the volume of a cude and rectangle

anonymous · Answer

you first need to get the base area and height of the 2 figures originally given. 

 then find the volume of the cone that fits exactly inside the cylinder. 
 the cone would have the same base area as the cylinder as well as the same height, 
 so just plug that into the area of cone formula: V = 1/3 * basearea * height 

 the pyramid would likewise have the same base area and height 
 plug those values in V = 1/3 * basearea * height 
 and subtract those 2 values

Volume = L x W x H

L = Length
W = Width
H = Height

Surface Area = 2(l x w) + 2 (L x h) + 2 (w x h)
