- [latex]S=2LH+2LW+2WH[/latex]

**Volume and Surface Area of a Cube**- [latex]V={s}^{3}[/latex]
- [latex]S=6{s}^{2}[/latex]

**Volume and Surface Area of a Sphere**- [latex]V=\Large\frac{4}{3}\normalsize\pi {r}^{3}[/latex]
- [latex]S=4\pi {r}^{2}[/latex]

**Volume and Surface Area of a Cylinder**- [latex]V=\pi {r}^{2}h[/latex]
- [latex]S=2\pi {r}^{2}+2\pi rh[/latex]

**Volume of a Cone**- For a cone with radius [latex]r[/latex] and height [latex]h[/latex] :Volume: [latex]V=\Large\frac{1}{3}\normalsize\pi {r}^{2}h[/latex]
