Answer 3

are you there?

Answer 4

@iGreen

Answer 5

yes

Answer 6

a cube has all 3 dimensions equal
what is the formula for the volume of the pyramid?

Answer 7

@zoejay1

Answer 8

the formula for a pyramid is lwh/3

Answer 9

Note that the volume of a cube is s*s*s (side times side times side, or s^3).

So that means: 54 = s^3
What is the length of a side of the cube?

Answer 10

sorry, i'm getting all of your repliess late for some reason

Answer 11

volume of pyramid is 1/3 the volume of the cube
because wow i can explain this one
B = length * width and because the cube fits then the length and the width are equal
the height is also the same as the cube since the cube fits
the volume of pyramid is 1/3 *(l^2)*l = 1/3*l^3
volume of the cube is l^3 for a cube all the sides are equal
l = length

Answer 12

@zoejay1 your reply is confusing, i don't understand it

Answer 13

@amistre64 @phi @ganeshie8 please help

Answer 14

I think they mean that this is the volume of the pyramid, so solve that and you'll get you answer. 1/3 *(l^2)*l = 1/3*l^3

Answer 15

your*

Answer 16

Ok, so I put "A cube has 3 dimensions that are equal to each other. The volume of a pyramid is V=1/3(b)(h). Using that information, we can say that the volume of the pyramid would be 1/3 of the volume of the cube. With "l" equaling length, we can say: 1/3*(l^2)*l >>> 1/3*l^3. Since the volume of pyramid equals 1/3 the volume of cube, 1/3*54=18. "

Would that be correct?
