Question

a cubical box has edge 10cm and another cuboidal box 2.5 cm long, 10cm wide and 8cm high wich box has greter lateral surface area and by how much?​

Answer 1

Lateral surface area of cubical box = 4a2 = 4 x 102 = 400 cm²

Lateral surface area of cuboidal box = 2h (l + b)

= 2 x 8(12.5 +10)

= 16 X 22.5

= 360 cm²

Thus, lateral surface area of cubical box is greater by

Thus, lateral surface area of cubical box is greater by

(400 cm² - 360 cm²) = 40 cm²
