How to find the surface area and volume of a cube or cuboid

The edge length of a cube is algebra (expressed by letters) a, the surface area is expressed as a * a * 6, read as the square of six a, and the volume is expressed as a * a * a, read as the cube of A
The length of a cuboid is expressed as a, the width as B, the height as h, and the surface area as (AB + ah + BH) * 2, which is read as the sum of length multiplied by width, length multiplied by height, width multiplied by height multiplied by height multiplied by two. The volume is expressed as ABH = a * b * H

The surface area of a cuboid and the volume of a cube
Surface area and volume of cuboid
A cube

The surface area of the cuboid is equal to (L * W + L * H + W * h) * 2 Volume length * w * H
The surface area of cube is equal to edge length * edge length * 6 Volume edge length * edge length * edge length
