Question

Which equation can you use to solve for the volume of the cake?

A. 60 × 40 × 30 × 10 = V

B. (30 + 60 + 10) + (30 × 60 × 10) = V

C. (40 × 60 × 10) + (30 × 60 × 10) = V

D. (30 × 60 × 10) + (30 × 40 × 10) = V

Answer 1

C. (40 × 60 × 10) + (30 × 60 × 10) = V

Explanation:

Picture of the cake can be found in the attachment below :

To solve, we resolve the cake into two distinct boxes :

The lower which is lateral sits parallel, whose volume, = (length * width * height) = (60 * 30 * 10)

And the other which sits vertically ;

Volume = (length * width * height) = (10 * 60 * 40)

Then, we add;

Overall volume:

(60 * 30 * 10) + (10 * 60 * 40)
