The shoebox has a length of 30 cm, a width of 10 cm, and a height of 8 cm. Determine how many square centimeters of gift-wrapping paper are needed to wrap the shoebox
•••••••••••••••••••••••••••••••••••••••••••••••••••••••
[tex]\text{Top and Bottom:} & \quad 2 \times (30 \, \text{cm} \times 10 \, \text{cm}) = 2 \times 300 \, \text{cm}^2 = 600 \, \text{cm}^2 \\ \text{Front and Back:} & \quad 2 \times (8 \, \text{cm} \times 10 \, \text{cm}) = 2 \times 80 \, \text{cm}^2 = 160 \, \text{cm}^2 \\ \text{Sides:} & \quad 2 \times (8 \, \text{cm} \times 30 \, \text{cm}) = 2 \times 240 \, \text{cm}^2 = 480 \, \text{cm}^2 \\ \text{Total Surface Area:} & \quad 600 \, \text{cm}^2 + 160 \, \text{cm}^2 + 480 \, \text{cm}^2 = 1240 \, \text{cm}^2 [/tex]
[tex]\text{Total surface area} = 2(300 \, \text{cm}^2) + 2(80 \, \text{cm}^2) + 2(240 \, \text{cm}^2) = 1240 \, \text{cm}^2[/tex]
