Answer:
<h2><u><em>
3 cm</em></u></h2>
Step-by-step explanation:
if the volume of a cube is 27cm³ what are the dimensions of the cube
Cube Volume = l³
we use the inverse formula
∛V = l
so
∛27 =
3 cm
Let x be the width of the sidewalk and the area becomes:
A=LW and L=6+2x and W=4+2x now we have
A=(6+2x)(4+2x) and we are told that A=48ft^2
48=24+20x+4x^2
4x^2+20x-24=0
4(x^2+5x-6)=0
x^2+5x-6=0
x^2-x+6x-6=0
x(x-1)+6(x-1)=0
(x+6)(x-1)=0
So x=-6, 1, however since x is a measurement it must be positive thus
x=width=1 ft is the only possible solution.
7000 because 10 groups of 700 equals 7000
