Cube

Area formula: $A = 6a^2$; Volume formula: $V = a^3$.

Rectangle Prism

Area formula: $A = 2(lw + lh + wh)$; Volume formula: $V = l \times w \times h$.

Cone

Area formula: $A = \pi r(r + \sqrt{h^2 + r^2})$; Volume formula: $V = \frac{1}{3} \times \pi r^2 h$.

Square-Based Pyramid

Area formula: $A = b^2 + 2b \times \sqrt{\frac{b^2}{4} + h^2}$; Volume formula: $V = \frac{1}{3} \times b^2 \times h$.

Triangular Prism

Area formula: $A = bh + (l \times (a + b + c))$; Volume formula: $V = \frac{1}{2} \times b \times h_{base} \times l$.
