To find a common denominator you have to find a number that both can be divided by in this case, 15. So both can be set to 15. However the numerators must also be changed. Since 15 divided by 5 is 3, the numerator 2 should be multiplied by 3 to get 6. Then since 15 can be divided by 3 to 5, you multiply 5 to the numerator 1 to get 5.

Then do
6/15 - 5/15 to get 1/15

Find the volume and explain please ASAP.

olya-2409 [2.1K]

Answer:

1395in^3

Step-by-step explanation:

First find the volume of the cuboid, 15in x 9in x 7in = 945in^3

Then find the volume of the rectangular pyramid using the formula V=lwh/3, the total height is 17in so subtract the height of the cuboid from the total height, giving you 10in.

V=(15in)(9in)(10in)/3 = 450in^3

450in^3 + 945in^3 = 1395in^3
