Hey Kid!
Given:Length 14 cmWidth 7 cmHeigth 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 cm²SA = 265.72 cm²
Hope this helps!
