Question

7. Joy is (4x + 5) years old. Her brother Michael is (3x - 2) years younger than her sister. Then write an expression that represents Michael's age.​

Answer 1

Answer:

Cube Cuboid

Total Surface Area = 6(side)2 Total Surface area = 2 (Length x Breadth + breadth x height + Length x height)

Lateral Surface Area = 4 (Side)2 Lateral Surface area = 2 height(length + breadth)

Volume of cube = (Side)3 Volume of the cuboid = (length × breadth × height)

Diagonal of a cube = √3l Diagonal of the cuboid =√( l2 + b2 +h2)

Perimeter of cube = 12 x side Perimeter of cuboid = 4 (length + breadth + height)
