Question

the lateral surface area of a cube is 100 cm sq then it's volume is​

Answer 1

Answer:

125 cu. cm

Step-by-step explanation:

LSA = 4a²

100 = 4a²

100/4 = a²

25 = a²

5 = a

Volume = 5 × 5 × 5

Volume = 125

Answer 2

Step-by-step explanation:

$\: formula \: of \: lateral \: surface \: area = {4a}^{2}$

lateral surface area of cube = 100cm

${a}^{2} = \frac{100}{4} = 25$

then a = √25=5

volume of cube

$= { {a}^{3} }$

${5}^{3} = 125$
