1.

The total surface area of a cube is 600 m^2. Find the side length and lateral surface area of the cube.

Answer»

side=10
LATERAL surface AREA=400m²

total surface area of CUBE =600m² (GIVEN)

formula=6a²

6a²=600

a²=600/6

a²=100

a=10(side of cube)

To find lateral surface area

formula=4a²

4a² (a=10)

4×10²

400
