Arectangular pyramid fits exactly on top of a rectangular prism. the prism has length 15 cm, width 5 cm, and height 7 cm, and the pyramid has height 13 cm. find the volume of the composite space figure. a) 1500 cm3 b) 500 cm3 c) 2275 cm3 d) 850 cm3

D.

Step-by-step explanation:

We have been given that a rectangular pyramid fits exactly on top of a rectangular prism. The prism has length 15 cm, width 5 cm, and height 7 cm, and the pyramid has height 13 cm.  

The volume of the composite figure will be equal to the volume of rectangular pyramid plus the volume of rectangular prism.  

, where,

l = Length,

w = Width,

h = Height

Therefore, the volume of composite figure will be 850 cubic cm and option D is the correct choice.

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.

it goes right
