Add the areas of all the faces (Flat sides).
You measure the sides, and multiply the top and side.
total surface area is all of the area. ex. for a square pyramid it would be the area of the square on the bottom and the four triangle sides lateral surface area is all the surface area EXCEPT the base. ex. for a square pyramid it would be the area of the four sides of the pyramid. the bottom square is NOT included. for a triangular prism it would be the area of the three rectangle sides, NOT the two triangular sides
To calculate the surface area of a brick, you would find the surface area for each of the 6 sides, then add them together. To find the surface area of one of the faces/sides, you would multiply the length of the face in question by the width of that same face. If this is a regular brick, then the sides should match up, meaning if you do one side, then the opposite side should be the same surface area. To find the volume, you multiply the height of the brick by the length of the brick by the width of the brick.
To calculate the surface area of the equilateral triangular-based prism, you need to calculate the area of the equilateral triangle and all the other sides of the prism. The total area of all the phases will give the total surface are of an equilateral triangular based prism.
To calculate the surface area of a truncated pyramid, you first take the surface area of each side. That would be the base time the straight height. If it is a 4 side pyramid with equivelant sides, multiply that answer by 4.
You can think of a square prism as a die, having six sides. So you need the length of one side, 's'. That side's [surface] area is s2 With six sides, the cube's surface area is simply: 6s2
To calculate the area of the front surface of a box, you would multiply the width of the box by the height of the box. This calculation gives you the area of the rectangular front surface.
If a cube has sides of length x cm then area = 6x2 cm2 and volume = x3 cm3
The surface area of a prism is the sum of the areas of each of its sides, plus the two bases. As the number of sides, and their shapes are indeterminate, there is no specific formula. The general formula is (2 x base area) + (perimeter x length)
Multiply the surface area by the volume Also stop cheating ur hw
You need to:* Calculate the surface area * Calculate the volume * Divide the surface area by the volume
