How do you calculate surface area and volume?
Cuboid
- Lateral Surface Area = 2(lh + bh) = 2 (l + b) h.
- Total Surface Area = 2(lb + bh + lh)
- Volume = l x b x h.
What is a formula of surface area?
Surface Area Formulas Add up all areas. SA=2B+2πrh. Find the area of the base, times 2, then add the areas to the areas of the rectangle, which is the circumference times the height. SA=4πr2.

What is CSA and TSA of sphere?
Surface area (TSA) = CSA = 4πr2. Hemisphere : Curved surface area(CSA) = 2 π r2. Total surface area = TSA = 3 π r2.
What is the formula of surface area of cuboid?
Solution: As we know, the total surface area of a cuboid, S = 2 (lb + bh + lh) and the lateral surface area of a cuboid is 2h(l + b). Therefore, the total surface area of cuboid and lateral surface area of a cuboid is 108 in2 and 60 in2 respectively.
What is the volume of surface area?
Surface area and volume are calculated for any three-dimensional geometrical shape. The surface area of any given object is the area or region occupied by the surface of the object. Whereas volume is the amount of space available in an object.
How do you find the surface area of a 3D shape?
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.
How to calculate surface area from volume?
Method 2 of 2: Calculating the Surface Area Knowing the Volume Download Article Find the volume of the cube. Let’s say that the volume of the cube is 125 cm 3. Find the cube root of the volume. To find the cube root of the volume, just look for a number that can be cubed to become the volume, or Plug this answer into the formula for finding the surface area of a cube. Just do the math.
How do you calculate volume area?
Method 2 of 3: Finding Volume from Surface Area Find your cube’s surface area. While the easiest way to find a cube’s volume is to cube the length of one of its sides, it’s not the only way. Divide the cube’s surface area by 6. Since the cube has 6 faces with equal area, dividing the cube’s surface area by 6 will give you the area of Take the square root of this value.
What are all the different formulas for volume?
Volume Formulas r = Radius of the circular base d = Diameter of the circular base h = Height of the cylinder
How do you find the volume of a surface?
Assuming you know the length, width and height of the prism (l, w, and h), you would multiply the three values together to get the volume, or you would find twice the sum of (lw + lh + wh) to find the surface area.
