A) 9, 8 and 10 cm |
B) 12, 6 and 10 cm |
C) 18, 4 and 10 cm |
D) 30, 2 and 12 cm |
A) 9, 8 and 10 cm |
Volume of the cuboid = \( \Large 720 cm^{3} \)
Height of the cuboid
= \( \Large \frac{Volume \ of \ the \ cuboid}{Base \ area \ of \ the \ cuboid} \)
= = \( \Large \frac{720}{72} = 10 cm \)
Surface area of the cuboid
= \( \Large 2 \left(lb + bh + hl\right) \)
= \( \Large 2 \left(9 \times 8 + 8 \times 10 + 10 \times 9\right) \)
= \( \Large 2 \left(72 + 80 + 90\right) \)
=\( \Large 2 \times 242 \)
= \( \Large 484 cm^{2} \)
Therefore, It is obvious that length, breadth and height of the cuboid is 9 cm, 8 cm and 10 cm.
