A rectangular water tank is 80 m long, 50 m wide and 60 m height. If the depth of water in the tank is 45 m, find the volume of water required to
completely fill the tank?*

A)240,000cm3
B)60,000cm3
C)180,000cm3
D)120,000cm3

Step-by-step explanation:

80 x 50 x 60 is volume of tank

240000

Water is already filled to 45 so volume up to that is

80x 50 x 45 = 180000

Subtract to find the difference needed to fill tank

240000 - 180000 = 60000

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
