Question

the total surface area of a cube is 600 m sq• find the side length and lateral surface area of a cube​

Answer 1

Answer:

Step-by-step explanation:

Given T.S.A. of a cube as 600 cm  2  , we have to find its L.S.A. But we know T.S.A. = 6l  2 , where l is the length of the cube. Hence 600=l  2   or l  2  =100 units. Taking square-root, we get l=10cm. But we also know that L.S.A. =4l  2

. Hence,

L.S.A. =4×10×10=400cm
