# What is the lateral surface area of a rectangle?

## What is the lateral surface area of a rectangle?

The formula for the lateral surface area of a rectangular box, also called a cuboid, is 2h(l + w), where l = length, w = width, and h = height.

**How do you find the surface area of a rectangle?**

To find the area of the rectangle, just multiply the two edges together. Area (bottom edge) = length times width = lw. Going back to our example, the area of the bottom face is 4 inches x 3 inches = 12 square inches.

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

Also, the lateral surface area of a rectangular prism can be calculated using the formula, LSA of rectangular prism = 2(l + b)h.

### What is LSA formula?

The lateral surface area of cylinder is expressed as LSA = 2πrh. Where r is the radius of a circular base of the cylinder, h is the height of the cylinder, and π (pi) is a constant term with a value of 3.14 or 22/7.

**What is lateral area formula?**

Formulas for Lateral Surface Area length) = 2 × (lb + bh + hl). The total surface area of a cube is given by 6 × (side)2. The lateral surface area of a cuboid is given by 2(length + breadth) × height. Similarly, the lateral surface area of a cube of side “a” is equal to 4 × (side)2.

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

When a prism has its bases facing up and down, the lateral area is the area of the vertical faces. (For a rectangular prism, any pair of opposite faces can be bases.) The lateral area of a right prism can be calculated by multiplying the perimeter of the base by the height of the prism.

## What is the formula for finding the surface area of a rectangular prism?

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 lateral area?**

You can find the lateral area of a solid with parallel bases by multiplying the perimeter of the base — the length around the edge of the base — by the solid’s height. The perimeter of a cube’s base is equal to four times the length of one of the cube’s edges, s.

**What is the formula for calculating surface area?**

Total Surface Area. You can combine the formulas for the base area and lateral area into the equation for the calculation for surface area: SA = (2 x pi x r^2) + (h x 2 x pi x r).

### How do you calculate lateral area of cylinder?

How To Calculate lateral & total area of a cylinder. Steps involved in calculating the lateral surface and total area are: Consider a cylinder with radius r, height h. Then to find lateral area we need the formula 2*pi*r*h, circumference – 2*pi*r, total area 2*pi*(r+h) and area of circle (pi^2)*r.

**How do you calculate the surface area of a triangle?**

To find the area of the triangular faces, use the formula A = 1/2bh, where A = area, b = base, and h = height. Once you have the areas of all sides and faces, you simply add them together to get the surface area.
