The dimensions of a cuboid are 15cm, 12cm and 10cm then fin
i) surface area. li) Lateral surface area iii) length of diagonal​

Answer 1

Answer:

Lateral surface area

Step-by-step explanation:

The dimensions of a cuboid are 15cm, 12cm and 10cm then fin

Answer 2

Answer:

surface area of cuboid = 2(lb+bh+hl)

= 2(15×12+12×10+10×15)

=2(180+120+150)

=2(450)

= 900 cm²

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

=2(15+12)×10

=2×27×10

=540 cm²

Diagonal of cuboid = √l²+b²+h²

=√(15²+12²+10²)

=√(225+144+100)

=√469

= approx 21.6 cm
