Key Formulas
Length of a Diagonal of a Cube
d = 
= s
where s is the
length of one edge of the cube.
= s where s is the
length of one edge of the cube.Length of a Diagonal of a Rectangular Solid
d = 
, where l is the
length, w is the width, and h is
the height of the rectangular solid.
, where l is the
length, w is the width, and h is
the height of the rectangular solid.Surface Area of a Cube
Surface area = 6s2,
where s is the length of one edge.
Surface Area of a Rectangular Solid
Surface area = 2lw + 2lh +
2wh, where l is the length, w is
the width, and h is the height.
Surface Area of a Cylinder
Surface area = 2πr2 +
2πrh, where r is the radius
and h is the height.
Surface Area of a Sphere
Surface area = 4πr2,
where r is the radius.
Lateral Surface Area of a Cone
Lateral surface area = πrl,
where r is the radius and l is
the lateral height of the cone.
Surface Area of a Cone
Surface area = πr2 +
πrl, where r is the radius
of the base and l is the lateral height.
Volume of a Cube
Volume = s3,
where s is the length of one edge.
Volume of a Rectangular Solid
Volume = lwh, where l is
the length, w is the width, and h is
the height.
Volume of a Prism
Volume = Bh, where B is
the area of the base and h is the height.
Volume of a Cylinder
Volume = πr2h,
where r is the radius of the circular base and h is
the height.
Volume of a Cone
Volume = 
πr2h,
where r is the radius and h is
the height.
πr2h,
where r is the radius and h is
the height.Volume of a Pyramid
Volume = 
Bh,
where B is the area of the base and h is
the height.
Bh,
where B is the area of the base and h is
the height.Volume of a Sphere
Volume = 
, where r is
the radius.
