Question

. Total surface area of a cube is 5400 sq.cm. Find the length of edge of cube.

Answer 1

Answer:

surface area of the cube is 6a2 =5400 .then A2=5400/6=900.then a=✓900=30

Answer 2

Answer:

total surface area of cube =5400

therefore, total surface area =6L (square)

5400 = 6L(square)

6L( square) =5400

L(square) = 5400 divided by 6

L(square)=900

√900 = 30

therefore, the length of the edge is 30
