Question

15. A rectangular tank is 110 cm wide and 70 cm deep. If it can contain 770 litres of water, what is the length of the tank
​

Answer 1

Answer:

Length of Tank = 1000 cm

Step-by-step explanation:

We Have :-

A rectangular tank is 110 cm wide and 70 cm deep. If it can contain 770 litres of water

To Find :-

what is the length of the tank

Formula Used :-

Volume of Cuboid = Length × Breadth × Height

Solution :-

Volume = L × B × H

770000 = L × 110 × 70

L = 770000 / 770

L = 1000 cm

Length of Tank = 1000 cm

Answer 2

$\huge {\red{\boxed{ \overline{ \underline{ \mid\mathfrak{An}{\mathrm{sw}{ \sf{er}} \colon\mid}}}}}}$

• Breadth (B) = 110 cm
• Height (h) = 70 cm
• Volume of water in tank = 770 l

Solution :

Volume = 770 = 770 * 1000 = 770000 cm³

Formula for Volume of cuboid is :

$\large \star{\boxed{\sf{Volume \: = \: l \: \times \: B \: \times \: h}}} \\ \\ \implies {\sf{770000 \: = \: 110 \: \times \: 70 \: \times \: l}} \\ \\ \implies {\sf{7700 \: \times \: l}} \\ \\ \implies {\sf{l \: = \: \dfrac{770000}{7700}}} \\ \\ \implies {\sf{l \: = \: 1000}} \\ \\ \large {\boxed{\sf{Length \: = \: 1000 \: cm}}}$
