Question

A rectangular pyramid fits exactly on top a rectangular prism. Find the volume of the composite square figure if the prism has length, 17cm, width 5cm, height 11 cm and the pyramid has a height of 12 cm. WORTH 50 POINTS WORTH 50 POINTS WORTH 50 POINTS

Answer 1

I don't know the answer as I don't have this sum. sorry

Answer 2

Answer:

Volume of composite space = 1275 cm³

Step-by-step explanation:

Missing point in question:-Find Volume of composite space?

For Prism,

Length l = 17 cm

Width w = 5 cm

Height h = 11 cm

As Rectangular pyramid fits exactly on top of the prism, length and width of prism is same for the base of the pyramid.

for Pyramid

Length l = 17 cm

width w = 5 cm

height h = 12 cm

Volume of composite space = Volume of prism + Volume of Pyramid

Volume of Prism Vpr = l × w × h

∴ Vpr =  17 × 5 × 11

∴ Vpr = 935 cm³   ....(1)

Volume of rectangular Pyramid Vpy = (l×w×h) / 3

∴ Vpy = (17 × 5 × 12) ÷ 3

∴ Vpy = 340 cm³  ....(2)

From 1 and 2, Volume of composite space,

V = Vpr + Vpy

∴ V = 935 + 340 = 1275

∴ V = 1275 cm³
