Question

If the length is9cm, breadth is10 cm and volume of cuboid is 1800cm. find the height and total surface area of cubiod​

Answer 1

20cm = h

TSA = 940cm^2

Step-by-step explanation:

volume of cuboid = 1800

l × b × h = 1800

9 × 10 × h = 1800

$h = \frac{1800}{9 \times 10} = \frac{200}{10} = 20cm$

TSA of cuboid = 2(lb + bh + hl)

= 2(9×10 + 10×20 + 20×9)

= 2(90 + 200 + 180)

= 2(470)

=940cm^2
