Answer:
2). Volume = 14400 feet³
3). Volume = 157.5 ft³
Step-by-step explanation:
Both the figures given in the sheet attached are a rectangular pyramid and a triangular prism.
2). In this part of the question solid given is in the shape of an rectangular pyramid.
Volume of this oblique pyramid = [tex]\frac{1}{3}(\text{Base})(\text{Height})[/tex]
Here 'B' = area of the base
h = height of the pyramid
Volume = [tex]\frac{1}{3}(25\times 36)\times 48[/tex]
= 14400 cubic feet
4). Volume of a triangular cone = (Area of the triangular base)×(height)
= [tex][\frac{1}{2}(\text{Base})(\text{height})]\times {\text{height of the prism}}[/tex]
= [tex]\frac{1}{2}(7\times 9)\times {5}[/tex]
= 157.5 ft³
