Step-by-step explanation:

HEY MATE

HERE IS YOUR ANSWER

=>TSA OF CUBE = 6a² =1350

6a²=1350

a²= 1350/6 => 225

a =15 cm

therefore : edge of a cube is 15 cm

VOLUME OF A CUBE IS =a³

a³= 15³

15³ => 3375

THEREFORE THE VOLUME

OF CUBE IS 3375 cubic cm

 \bf \underline{Given} \\  \sf \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \: \bullet \: TSA \: of \: cube = 1350m {}^{2} .  \\  \\  \bf \underline{To \: Find}   \\  \sf \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \: \bullet \:Volume \: of \: cube. \\  \\ \bf \underline{Formula} \\ \sf \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \: \bullet \:Volume \: of \: cube = (side) {}^{3}  \\ \sf \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \: \bullet \:TSA\: of \: cube = 6(side) {}^{2} .

 \\ \bf \underline{Solution} \\ \sf Total \: surface \: area \: of \: cube = 6(side) {}^{2}  \\  \sf1350m {}^{2}  = 6(side) {}^{2}  \\  \sf side {}^{2}  =  \frac{1350}{6}   m\\  \sf side {}^{2}  = 225m \\  \sf \: side =  \sqrt{225}  \\  \sf \: side = 15m

 \\ \implies \bf Volume \: of \: cube = (side) {}^{3}  \\  \to \sf Volume \: of \: cube = (15)  {}^{3}  \\  \to  \sf\: Volume \: of \: cube = 15 \times 15 \times 15 \\ \small  \boxed {\boxed {\tt \green {\to\sf = 3375m {}^{3}   }}}

 \bf \therefore \underline{volume \: of \: cube = 3375{}{3}}
