To find the weight of aluminum for

Answer to Problem 61A
Given information:
A casting is given with dimensions in millimeter as below.
Calculation:
Here we observe that the casting is made by putting a smaller cube on top of a larger cube. So, volume of casting will be equal to summation of volume of both cube.
As we know that volume of a cube is given by -
Here, side length of the smaller cube is
So, volume of the smaller cube will be -
Similarly, side length of the larger cube is
So, volume of the smaller cube will be -
Total volume of casting
Now, weight of aluminum is
So, weight of aluminum for
This is the weight of aluminum for one casting.
Therefore, weight of aluminum for
