The volume of a rectangle prism is 200. If one dimension doubled, second dimension reduced by 2/3, and third dimension increase by 6x its original length.

Question

what is the new volume?

I'm really confuse if this is correct, but I got 1600 unit cubed

Someone please help me.

Answer 1

Volume of a Rectangular prism = L * B * H = 200

2L * ( B - 2/3 ) * ( 6H ) {Since, doubled, reduced by 2/3rd, increased by 6 }

2L * ( 3B - 2) / 3 * (6H)

4L H * ( 3B - 2)

12 LBH - 2LH

12 (200) - 2LH

Here, we need new volume of rectangular prism to get the value of LH, then by substituting LH in original volume which is LBH, we get B.

Think so the question is incomplete.
