Answer:
C. (40 × 60 × 10) + (30 × 60 × 10) = V
Step-by-step 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)
Answer:

Step-by-step explanation:
The tunnel, the ground and the depth of the tunnel form a right angle triangle.
The length of the tunnel is the hypotenuse of the right triangle that has been formed.
Let the length of the tunnel be
.
Using the sine ratio, we obtain;

The length of the opposite side is 
We substitute the given values to obtain;


We cross multiply to obtain;


Therefore the correct answer is C.
The length is 6 inches.
The width is 1 foot = 12 inches.
The perimeter is (6 + 12 + 6 + 12) = 36 inches (3 feet) .
"14 inches" is false.
