ст
Surface area =

52 cm²

Step-by-step explanation:

For Rectangle

Length (l) = 2 cm;

Width (b) = 3 cm;

Height (h) = 4 cm

Surface area of Rectangle

= 2 * (lb + bh + hl)

= 2 * (2*3 + 3*4 + 4*2) cm

= 2 * (6 + 12 + 8) cm

= 2 * (26) cm

= 2 * 26 cm

= 52 cm²

Thus, the Surface area of rectangle is 52 cm²
