Answer 2

lookup the formula for volume of rectangular pyramid

Answer 3

V=lwh/3.
Thats the formula but i dont know how to do it because we dont have height.

Answer 4

why do you need height ?

Answer 5

correct, were trying to find height. but then how do i find the volume of rectangular pyramid without the height?

Answer 6

You don't need to find something when it is given to you already

Answer 7

read the question again
you're given volume

Answer 8

yes i know but you said to find formula for volume of rectangular pyramid, which is V=lwh/3. but idk what do next if we already have the volume, width and length

Answer 9

You can use that formula to find the height

Answer 10

Plugin the given values in that formula first

Answer 11

756=(9)(14)/3

Answer 12

who ate `h` ?

Answer 13

756=(9)(14)( `h`)/3

Answer 14

right ?

Answer 15

oh lol, correct, i just thought since we dont know H theres no point of it being there, my bad

Answer 16

We must follow the rules of math, not our wishes ;)

Answer 17

see if you can solve `h` from above equation

Answer 18

756 = 42 h

Answer 19

You want h

Answer 20

756=42h
756/42=18
So the answer is D

Answer 21

Yes!
As you can see, the formula V = lwh/3 can be used to solve any of the four quantities, V or l or w or h, when you know any 3 quantities.

Answer 22

Yep i understand how to do it now, thanks again :)

Answer 23

In the present problem, you knew V, l, and w; the formula helped you find the unknown h
