Question

What is formula of curved surface area of cube and cuboid

Answer 1

Answer:

Formulas Cube Cuboid

Surface Area 6l2 2(lb + bh +lh)

Lateral Surface Area 4l2 2h(l +b)

Volume l3 l × b × h

Diagonal Length √3l √( l2 + b2 +h2)

Answer 2

The formula for the curved surface area of the cube is 4a²  

The curved surface area of the Cuboid is 2h (l + w).    

Given:

The curved surface area of cube and cuboid

To find:

What is the formula for the curved surface area of a cube and cuboid

Solution:

What is a Cuboid?

A cuboid is a three-dimensional object that is surrounded by six rectangular planes of varying length, breadth, and height. Anything in the shape of a rectangle, such as a box, brick, etc. could be a cuboid.

If l, w, and h are the Length, Width, and Height of a cuboid

The formula for Curved Surface Area is given by

Curved Surface Area of Cuboid =  2h (l + w) square units

What is a Cube?  

A solid three-dimensional figure with six square faces, eight vertices, and twelve edges is called a cube. Also said to be a conventional hexahedron. For example 3 × 3 Rubik’s cube.

If 'a' is the side of the cube then the formula for the Curved Surface Area of the cube is given by

Curved Surface Area = 4a²

Therefore,

The formula for curved surface area of the cube is 4a²  

The curved surface area of the Cuboid is 2h (l + w).
