## What is the surface area of a rectangular cube?

A cube is a rectangular prism where all its sides are the same. The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.

**How do you find the surface area of a long rectangular prism?**

What Is the Formula for Calculating the Surface Area of a Rectangular Prism? The formula to calculate the total surface area of a rectangular prism is given as, TSA of rectangular prism = 2(lb × bh × lh), where, l is length, b is breadth and h is the height of the prism.

### What is the total surface area of the cube with length 5cm?

(b) We know that the length of the edge of the cube is 5cm. Substituting a=5 in the formula 6a2, total surface area of the cube =6(5)2=150cm2.

**What is the formula of total surface area of a cube?**

The surface area of a cube = 6a2 where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, a is just the lenght of one side of a cube.

#### What is the total surface area of a cube whose side is 0.50 5 cm?

125cm2.

**How to find surface area of Cube and rectangular prism?**

We learned that a rectangular prism is a box where all the sides are rectangular and all the faces meet at a perpendicular angle. A cube is a rectangular prism where all its sides are the same. The formula to find the surface area of a rectangular prism is A = 2 wl + 2 lh + 2 hw, where w is the width, the l is the length, and the h is the height.

## How is the surface area of a cube equal to its total surface area?

Since the cube has six faces, therefore, the total surface area of the cube will be equal to sum of all six faces of cube. Since, the surface of the cube is in square shape.

**Which is the formula for total surface area?**

Total Surface Area = π (r 1 2 + r 2 2 + (r 1 * r 2 ) * s) = π [ r 1 2 + r 2 2 + (r 1 * r 2 ) * √((r 1 – r 2 ) 2 + h 2 ) ]

### How to calculate the surface area of a cuboid?

Total surface area of a cuboid = 2 × (area of three symmetrical faces) = 2 × (lb + bh+ hl) The curved surface of a cylinder, if opened along the diameter (d=2r) of the circular base can be transformed into a rectangle of length ‘2?r’ and height ‘h’.
