Question

0-2 Find the volume and the total surface area of a cuboid which is 15cm long,I2 cm wide and 4.5cm high ​

Answer 1

Step-by-step explanation:

length = 15 cm

Breadth = 12 cm

Height = 4.5 cm

There fore, volume of cuboid = l× b× h = 15× 12× 4.5 = 810 cubic cm

Now, totalSurface area of cuboid = 2 (lb + bh +hl) = 2 (15×12+ 12 × 4.5 + 4.5 × 15) = 2 ( 180 + 54 + 67.5)

= 2 (301.5)

= 603 sq. cm

I hope this will help you!

Answer 2

Answer:

Length= 15cm

Breadth= 12cm

Height = 4.5cm

Volume of the Cuboid= Length×Breadth×Height

= 15×12×4.5

= 810cm³

Total Surface Area of Cuboid= 2( lb+bh+lh)

=2( 15×12+12×4.5+15×4.5)

= 2(180+54+67.5)

= 2(301.5)

= 603cm²
