A. L = 2 (pl*pt*lt) = 2 (8 cm * 5 cm) + (8 cm * 3 cm) + (5 cm * 3 cm) = 2 (40 cm² + 24 cm² + 15 cm²) L = 2. 79 cm² L = 158 cm² b. V = p*l*t = 8 cm * 5 cm * 3 cm V = 120 cm³
L = (p.l) + t
= ( 8 x 5 x 3 ) cm
=
= 2 (8 cm * 5 cm) + (8 cm * 3 cm) + (5 cm * 3 cm)
= 2 (40 cm² + 24 cm² + 15 cm²)
L = 2. 79 cm²
L = 158 cm²
b. V = p*l*t
= 8 cm * 5 cm * 3 cm
V = 120 cm³
