Question

A rectangular tank with square ends has a length 1.5m greater than its width .The total length of all its edges are 20.4m.
Find the dimensions of the square end of the box and find its volume

Answer 1

so the total of all edges are 20.4m
There are 4 lenght which are 1.5m greater than the width.
The square ends have the same lenght and width.

I think 20.4 - (4*1.5) = 14.4m <- this is the total length if it was a cube.
A cube has 12 edge lines so 14.4 / 12 = 1.2m

The height would be 1.2m, same for the height.
The length would be 1.2+1.5 = 2.7m

Don't know if i'm right :P not the best at math.

Answer 2

just having ago at it myself .thanks for your reply.
