Question

the dimensions of a cuboid is 15 cm into 12 cm into 10 cm find its lateral surface area total surface area volume​

Answer 1

Answer:

lateral surface area=540 cm^2

Total surface area=900 cm^2

Given:

Length=15cm,breadth=12cm and height=10cm

To find:

Total surface area and lateral surface area

Solution:-

We know that

Lateral surface area of cuboid=2(l+b)h

=2(15+12)10

=2(27)10

=2×270

=540 cm^2

We also know that

Lateral surface area=2lb+2lh+2hb

=2×15×12+2×15×10+2×10×12

=360+300+240

=900 cm^2

Answer 2

Answer:

 900 cm2

Step-by-step explanation:

Lateral surface area of cuboid=2(l+b)h

=2(15+12)10

=2(27)10

=2×270

=540 cm^2

We also know that

Lateral surface area=2lb+2lh+2hb

=2×15×12+2×15×10+2×10×12

=360+300+240 is  900 cm2
