Area of rectangle box = 2,920 CM²

Step-by-step explanation:

Given:

Length = 42 Cm

Width = 20 Cm

Height = 10 Cm

Find:

Total area required to make box = ?

Computation:

Area of rectangle box = 2[LB + BH + HL]

Area of rectangle box = 2[(42 × 20) + (20 × 10) + (10 × 42)]

Area of rectangle box = 2[(840) + (200) + (420)]

Area of rectangle box = 2[1,460]

Area of rectangle box = 2,920 CM²
