A pyramid has a volume of 18 in3. If all measures of the pyramid are multiplied by 6, what will the volume be?

Question

amistre64 · Answer

how do we determine the volume of a pyrimad?

anonymous · Answer

LxWxH then divide by 3.

amistre64 · Answer

yep

so each part is times 6 bigger

l h w/3 = 18

l h w = 3(18)

if we times the other side by the appropriate value/s ... what do we do to the other side?

amistre64 · Answer

moving the 3 wasnt needed, but i seem to have felt like doing it anyways .... well move it back later

anonymous · Answer

I dont understand what you're asking.

amistre64 · Answer

apply the given information, 

all measures of the pyramid are multiplied by 6

resulting in 6L, 6W  and 6H

whats the new volume?

amistre64 · Answer

or think about it in this way:

since we know that LWH/3 = 18

6L 6W 6H/3 is our new volume

6^3  LWH/3  = new volume,  but LWH/3 is 18

6^3  18  = new volume
