V 5.5 m
Find the total surface area of the cuboids of length, breadth and height as given below:
(i) 12 cm, 10 cm, 5 cm
​

Answer 1

Answer:

460 sq cm

Step-by-step explanation:

L= 12 cm

B = 10 cm

H= 5 cm

total surface area of the cuboid = 2( LB +BH+HL)

2( 12×10+10×5+5×12)

= 2(120+50+60)

= 2(230)

= 460 sq cm

the total surface area of the cuboid= 460 sq cm
