Answer:
Volume of composite figure = 850 cubic cm.
Step-by-step explanation:
Given : 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.
To find : Find the volume of the composite space figure.
Solution : We have given that
Prism length 15 cm
Width = 5 cm.
Height = 7 cm.
pyramid height = 13 cm
Width = 5 cm
Length = 15 cm.
Volume of composite space = volume of prism + volume of pyramid .
Volume of composite space = (l b h )+( \(\frac{1}{3} length *width * height\) .
Plugging the values of length , width , height
Volume of composite figure = ( 15 5 7 ) +( tex]\frac{1}{3} 15 5 13)[/tex] .
Volume of composite figure = (525 ) +( 325)
Volume of composite figure = 850 cubic cm.
Therefore, Volume of composite figure = 850 cubic cm.
