Question 126814
Try this:
{{{V = (10)x*(4)x*(1)x}}} V = 1080 Cu m
{{{1080 = 10x*4x*x}}}
{{{1080 = 40x^3}}} Divide both sides by 40.
{{{27 = x^3}}} Take the cube root of both sides.
{{{3 = x}}}
The dimensions are:
Length: {{{10x = 10(3)}}} = {{{30}}}meters.
Width: {{{4x = 4(3)}}} = {{{12}}} meters.
Depth: {{{x = 3}}} + {{{3}}} meters.
Check:
{{{V = L*W*d}}}
{{{V = 30*12*3}}}
{{{V = 1080}}} Cu.meters.
