**How do you find the surface area of a geometric shape?**In

**byebyebimari**

The **surface area** of a solid figure is the sum of the outside **areas**. This means you have to find the **area** of all of the “pieces” that make up the solid figure. Find the **area** of each part which makes up the solid figure, Then add all of the **areas** together to get the total **area** of the OUTSIDE of the **geometric** solid.

.

Considering this, what is the formula for area of all shapes?

The most basic **area formula** is the **formula** for the **area** of a rectangle. Given a rectangle with length l and width w, the **formula** for the **area** is: A = lw (rectangle). That is, the **area** of the rectangle is the length multiplied by the width.

Likewise, what is the formula for finding the surface area of a triangle? To find the **area** of a **triangle**, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 **triangles**. For example, in the diagram to the left, the **area** of each **triangle** is equal to one-half the **area** of the parallelogram.

Also, what is the formula for finding the surface area of a cylinder?

**To find the surface area of a cylinder** add the **surface area** of each end plus the **surface area** of the side. Each end is a circle so the **surface area** of each end is π * r^{2}, where r is the radius of the end. There are two ends so their combinded **surface area** is 2 π * r^{2}.

How do you find the surface area and volume of a shape?

**Sphere Surface Area Formula and Sphere Volume Formula**

- Surface area = 4πr
^{2} - Volume =
^{4}⁄_{3}πr^{3} - Surface Area of a Prism = 2 × (Area of the base shape) + (Perimeter of base shape) × (d)
- Volume of a Prism = (Area of base shape) × d.
- Surface Area of a Box = 2(L × W) + 2(L × D) + 2(W × D)
- Volume of a Box = L × W × D.
