Question

The total surface area of a cube is 1350sq m find its volume

Answer 1

total surface area of cube is 6lsq

1350= 6×lsq
lsq=1350/6
lsq=225
l=15

to find volume,

volume of cube is l cube.
volume = 15×15×15
= 3375

plz mark as brainiest if help

Answer 2

Answer ;


Given Total Surface Area of Cube = 1350sq m


As we know that The formula to find the Total Surface Area of Cube is :

$= > \: 6 {(side)}^{2} \\ \\ \: so\: we \: can \: say \: that \: \\ \\ = > \: 6(side) {}^{2} = 1350 {m}^{2} \\ \\ = > \: (side) {}^{2} = \frac{1350}{6} \\ \\ = > \: (side) {}^{2} = 225 \\ \\ = > \: side \: = \sqrt{225 } \\ \\ = > \: side \: = 15m \\ \\ now \: side \: = 15m \: so \: volume \: of \: cube \: = \\ \\ = > \: {(side)}^{3} \\ \\ = > \: (15) {}^{3} \\ \\ = > \: 3375 \\ \\ therefore \: the \: volume \: of \: cube \: = 3375m {}^{3}$
