Frequently Asked Questions

The total area covered by the surfaces of a 3D solid.

The area of only the curved part of a solid.

The sum of all faces (curved + flat) of a solid.

The space occupied by a solid measured in cubic units.

To find materials needed to cover an object like paint or wrapping.

To find capacity, such as water tanks and containers.

Surface area \(\Rightarrow cm^2,\ m^2;\ Volume \Rightarrow cm^3,\ m^3\).

TSA = 2(lb + bh + hl).

Volume = l × b × h.

TSA = \(6a^2\).

Volume = \(a^3\).

CSA \(= 2\pi rh\).

TSA \(= 2\pi r(r + h)\).

Volume = \(\pi r^2h\).

\( l = \sqrt{r^{2} + h^{2}} \).
