How do you work out the total surface area of a pyramid?
The basic formula for the surface area of any pyramid, regular or irregular, is Total Surface Area = Base Area + Lateral Area. Don’t confuse “slant height” with “height.” The “slant height” is the diagonal distance from the apex of the pyramid to the edge of the base.
What is a formula of cylinder?
The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm. … Therefore, the volume of the cylinder is about 3016 cubic centimeters.
Is surface area and volume the same thing?
Surface area is a two-dimensional measure, while volume is a three-dimensional measure. Two figures can have the same volume but different surface areas. For example: … A rectangular prism with side lengths of 1 cm, 1 cm, and 4 cm has the same volume but a surface area of 18 sq cm.
How do you find the surface area and volume of a cube?
So for a cube, the formulas for volume and surface area are V=s3 V = s 3 and S=6s2 S = 6 s 2 .
What is the formula of cube?

What is the slant height of the pyramid?
The slant height of an object (such as a frustum, or pyramid) is the distance measured along a lateral face from the base to the apex along the “center” of the face. In other words, it is the altitude of the triangle comprising a lateral face (Kern and Bland 1948, p. 50).
How do you find the slant height?
The slant height can be calculated using the formula a^2 + b^2 = c^2. In the formula, a is the altitude, b is the distance from the center of the base to the point where the slant height segment starts, and c stands for the slant height.
What is the π?
Succinctly, pi—which is written as the Greek letter for p, or π—is the ratio of the circumference of any circle to the diameter of that circle. Regardless of the circle’s size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14.
What is TSA of cylinder?
Total Surface Area of Cylinder
The total surface area of a cylinder is equal to the sum of areas of all its faces. The Total surface area with radius ‘r’, and height ‘h’ is equal to the sum of the curved area and circular areas of the cylinder. TSA = 2π × r × h + 2πr2= 2πr (h + r) Square units.
