Question

If lateral surface area of cube is 1600 cm², then what it's edge ?​

Answer 1

Answer:

20 cm

Step-by-step explanation:

let a be the side of cube

since lateral surface area of cube = 4 a×a

so, 4a^2 = 1600

or, a^2= 400

therefore a= 20

hence, side of cube is 20 cm

Answer 2

LSA=1600cm^2
LSA=4s^2
1600=4s^2
1600/4=s^2
400=s^2
Root400=s
20cm=s
