Question

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

Answer 1

Answer:

100cm

Step-by-step explanation:

770 liters = 770000 cm3 = width x depth x length

Length = 770000 cm3 /(110cm x 70cm) = 100cm

Answer 2

Capacity of the water tank

Capacity of the water tank Width = 90 cm = 0.9 m

Capacity of the water tank Width = 90 cm = 0.9 mDepth = 40 cm = 0.4 m

Capacity of the water tank Width = 90 cm = 0.9 mDepth = 40 cm = 0.4 mLength =

Capacity of the water tank Width = 90 cm = 0.9 mDepth = 40 cm = 0.4 mLength = =capacity\width×depth

Capacity of the water tank Width = 90 cm = 0.9 mDepth = 40 cm = 0.4 mLength = =capacity\width×depth =0.576/0.9×0.4=1.600
