Answer 1

HEYA!

QUERY

IF THE TOTAL SURFACE AREA OF CUBE IS 135O SQUARE METRES FIND THE LENGTH AND BREADTH AND HEIGHT OF THE CUBE

SOLUTION

TOTAL SURFACE AREA OF THE CUBE = 1350 SQUARE METRES

WE KNOW THAT TOTAL SURFACE AREA OF THE CUBE IS

                           6a²

1350 = 6a²

$\frac{1350}{6}$ = a²

225= a²

a= $\sqrt{225}$

a= 15cm³

HOPE THIS HELPS
