Question

In figure, the shape of a solid csopper piece (made of two pieces with dimensions as shown in the figure) is shown. The face $ABCDEFA$ is the uniform cross section. Assume that the angle at $A,B,C,D,E$ and $F$ are right angles. Calculate the volume of the piece.

• A. $2145$
• B. $7414$
• C. $3545$
• D. None of these

Answer 1

The correct option is D None of these

Given:

$AB=2cm$

$IJ=5cm$

$JK=8cm$

$KL=3cm$

Volume of upper cuboid$=l\times b\times h$

$=22\times 2\times 5$

$=220c{m}^3$

Volume of lower cuboid$=FE\times EL\times DE$

$=(8+2)\times 22\times 3$

$=660c{m}^3$

Volume of copper piece$=(660+220)c{m}^3$

$=880c{m}^3$
