Volume and Surface Area
Cube
Volume: You have to multiply the height by the width by the length (W*L*H)
Perimeter: First , we multiply the perimeter by the height. Then, we add the area of the bases (in the case of the cube, there are two bases)
The perimeter is the sum of all sides.
Cylinder
Volume: For the volume we have to multiply Pi by the radius squared by the altitude. (π*r2*a)
Surface Area: You multiply the circumference by the altitude. Then, you add the area of the bases. (C*A + 2π*r2)
Pyramid
Volume: the volume is the same as the cube, just divided by 3
Surface Area: the area is the same as the cube with a few differences. When calculating the perimeter times the height divide by two. As the pyramid only has one base, add the area of that one base instead of two.
Cone
Volume: the same as the cylinder, divided by 3
Surface Area: the same as the cylinder with the same alterations as the pyramid.
