Question

(x). If each side of a cube is a, then its lateral
surface area is
sq. units.​

Answer 1

Answer:

4a² sq.units

Step-by-step explanation:

lateral surface area of a cube is the sum of the areas of the 4 sides (lateral sides) leaving the top and bottom areas.

each side is a square of side 'a' and hence the area of a single side is 'a²'.

so, area of the lateral sides ( which are equal sides) is nothing but sum of the 4 areas of the sides.

hence, we have 4a² sq.units as the lateral surface area of a cube.

Answer 2

Answer:

The lateral surface area =4a
