24$c^{4}$+72$c^{2}$+54
Formula surface area of a cube: 6$a^{2}$ Plug in the value of a : 6$(2c^{2}+3)^{2}$ Simplify: 6 ($2c^{2}$+3)(2$c^{2}$+3) FOIL method: 6[($2c^{2}$)($2c^{2}$)+($2c^{2}$)(3)+(3)(2$x^{2}$)+(3)(3)] Simplify: 6(4$c^{4}$+6$c^{2}$+6$c^{2}$+9) Combine like terms: 6(4$c^{2}$+12$c^{2}$+9) Distribute 6 to every term in the parenthesis: 24$c^{2}$+72$c^{2}$+54
