Question

Hi, I don't need this really fast, but I really don't understand how to do surface area and lateral surface area with rectangular prisms, triangular prisms and cylinders. Any tips will be greatly appreciated. I will give you brainlist. ( idk how to spell lol ) :)

Answer 1

Answer:

The volume of a pyramid

V=1/3⋅B⋅h

The area of the rectangle:

A=C⋅h

A=12.6⋅6

A≈75.6

To find the volume of a cylinder we multiply the base area (which is a circle) and the height h.

V=πr2⋅h

Answer 2

Answer:

The surface area is the area that describes the material that will be used to cover a geometric solid. When we determine the surface areas of a geometric solid we take the sum of the area for each geometric form within the solid.
