Question

1.Explain about 2D and 3D figures with examples.
2.Explain what is surface area and volumes with their units.

Answer 1

1 .A two-dimensional (2D) shape has only two measurements, such as length and height. A square, triangle, and circle are all examples of a 2D shape. ... One example of a 3D shapeis a rectangular prism, which is made up of four rectangles and two squares.

Answer 2

hey mate here is ur answer

The circle is a two-dimensional (2D) shape. It only has two measurements, such as length and height, and is usually called a 'flat' shape. The ball, however, is a three-dimensional (3D) shape because it has three measurements (length, height, and width) and is sometimes called a 'solid' shape.

In 3d shapes there is Total Surface Area,Curved Surface Area, volume
for ex- CSA of cube=4×side sqare,TSA=6×side sqare,volume =side cube.
i hope it is helpful for u
