Question

Find the surface area of cuboid whose length, breadth and height are 15cm ,10cm, and 20cm

Answer 1

Answer:

surface area of cuboid = 2(LB +BH+LH)

In the question it is given that , L= 15cm B= 10 cm and

H= 20cm

so, surface area = 2( 15×10 +10×20+20×15)cm2

= 2( 150 + 200+ 300)cm2

= 2 × 650cm2 = 1300cm2

surface area of cuboid = 1300cm2 @n$

Answer 2

Answer:

1300 cm^2

Step-by-step explanation:

CSA OF CUBOID= 2(LB+LH+BH)

= 2(15×10+15×20+20×10)

= 2(150+300+200)

= 2×650

= 1300 CM^2
