Question

PLEASE HELP 20 POINTS PLEASE GIVE EXPLANTION ​

Answer 1

Answer:

300 in³

Step-by-step explanation:

To calculate the volume of a composite solid, simply split it into smaller solids and calculate their separate volumes. The volumes of each of the individual solids are then added together to give the total volume of the composite solid.

Remember, the formula for volume is: l • w • h

12(length) x 5 (width) = 60 x 3(height) = 180 in

5(width) x 8(length) = 40 x 3(height) = 120 in

Now, finally we add up the answers.

180 + 120 = 300 in³

(*Don't forget to cube³ your answer since it's Volume)
