Question

find the surface area of a cuboid if its length is 15 and the breadth is 16 and the height is 12​

Answer 1

Answer:

25

formula = √(l×l + b×b + h×h)

=√15×15 + 16×16 + 12×12

=√225+ 256 + 144

=√625

= 25

Answer 2

Answer :

1224 cm or 12.24 m

Step-by-step explanation:

Surface Area of cuboid -: 2( length*width + length*height + width*height )

Given, length -: 15

breadth -: 16 cm

height -: 12 cm

So, according to the question,

2( 15*16 + 15*12 + 16*12 ) cm

2( 240 + 180 + 192 ) cm

2( 240 + 180 + 192 ) cm

2*612 cm
