What is total surface area of pyramid?
The lateral surface area of a regular pyramid is the sum of the areas of its lateral faces. The total surface area of a regular pyramid is the sum of the areas of its lateral faces and its base. =12pl where p represents the perimeter of the base and l the slant height. …
In this regard, How do you calculate the surface area?
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.
Regarding this, 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).

What is slant height of cone in above tank?
Since the base of a cone is a circle, we substitute 2πr for p and πr2 for B where r is the radius of the base of the cylinder. So, the formula for the lateral surface area of a right cone is L. S. A=πrl , where l is the slant height of the cone .
Which is longer height or slant height?
The slant height is going to be a bit more than the base depth because the distance from the corner of the base edge to the top peak (representing slant height) is greater than the distance from the center of the base edge straight up to the top peak (representing base depth). …
How do you change slant height to height?
Evaluate the equation from the previous step to yield the regular height. For example, if the slant height angle is 30 degrees and the slant height is 20 feet, then use the equation sin(30) = regular height / 20 feet. This yields 10 feet as the regular height.
