## What is the formula to find the total surface area of a cube?

The total surface area of a cube is the area covered by all the six faces of a cube. The formula to find total surface area of a cube is given as, Total surface area = 6a2, where, ‘a’ is the edge length of the cube.

## How do you find the total surface area?

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

**What is the surface area of a 3x3x3 cube?**

What is the surface area of a 3x3x3 cube? As you already know, a cube has six square faces. If each of those faces is 3 inches by 3 inches, then the area of each face is 3 × 3 = 9 square inches. And since there are six of them, the total surface area is 9 + 9 + 9 + 9 + 9 + 9 = 54 square inches.

### What is the surface area of a 9 cm cube?

486cm2

The side of the cube is given as 9 cm. To find the total surface area of the given cube, we have to substitute a=9 in the formula. Total surface area of the cube with side 9 cm is 6(9)2=486cm2 .

### What do you mean by total surface area?

The total surface area of a solid is the sum of the areas of all of the faces or surfaces that enclose the solid. The area of the rectangle is the lateral surface area. The sum of the areas of the rectangle and the two circles is the total surface area.

**What is the surface area of a 2x2x2 cube?**

What is the surface area of a 2x2x2 cube? The surface area is 24 (6 sides, each 2×2).

## What is the surface area of a polyhedra?

The surface area of a polyhedron is equal to the sum of the area of all of its faces. Said another way, the surface area is the total area covered by the net of a polyhedron.

## What is the total surface area of rectangle?

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 difference between surface area and total surface area?**

The lateral surface of an object is the area of all the faces of the object, excluding the area of its base and top. For a cube, the lateral surface area would be the area of four sides. Total surface area is the area of all the faces including the bases.
