It’s not just 3/4th of 128

#

Remember they are similar all sides are smaller so you have to account for that

#

Was I supposed to find the cube root of 128?

#

No

#

what was I supposed to do

serene bison Jul 22, 2023, 1:46 AM

#

All sides are 3/4th of their original sides

#

not just 1

#

What’s the formula to find the volume

#

LxWxH

#

Right and because they’re similar

#

The length of the smaller prism is 3/4th of the bigger prism
The width of the smaller prism is 3/4th of the bigger prism
And the height of the smaller prism is 3/4th of the bigger prism

#

Now put that into your formula

#

What do you get

#

You got 96 because you thought only one side was 3/4th of the original

#

But 3 of them are

#

So the actual volume is much smaller than what you put

#

Oh

#

Thx

#

Wait

#

How do I find the values of the shorter sides

#

I can’t js use 3/4 as the value

Multiply it by 3/4 3 times

sturdy narwhal Jul 22, 2023, 2:14 AM
