Given:

Length 14 cm

Width 7 cm

Heigth 1.66 cm

Lateral area = 2lh + 2wh

LA = 2 (14cm) (1.66cm) + 2 (7cm) (1.66cm)

LA = 46.48 cm² + 23.24 cm²

LA = 69.72 cm²

Surface area = 2 (wl + hl + hw)

SA = 2 (7cm*14cm) + 2 (1.66cm*14cm) + 2 (1.66cm*7cm)

SA = 196 cm² + 46.48 cm² + 23.24 cm²

SA = 265.72 cm²
