1.find the capacity of rectangular tone? in liters.
If you mean the volume of a rectangular solid, then (since you didn't specify, I will assume feet)
V = Lwh
L = 5.5, w = 3.5, h = 3.6
V = (5.5)(3.5)(3.6)
V = 69.3 cubic feet
To convert to liters
1 ft = 12 in
1 in = 2.54 cm
1000 cubic cm = 1 liter
1 ft * 12 in * 2.54 cm = 30.48 cm/ft
(30.48 cm/ft)^3 = 28316.85 cm^3/ft^3
Volume in liters = (vol. in ft^3 * 28316.85 cm^3/ft^3)/1000 L/cm^3
(69.3 ft^3 * 28316.85) = 1,962,358/1000 = 1962.358 liters
You can do the 2nd one.
2.Find total surface area of solid cube of volume: What cube?
3.A man earn $1200 and spends $450 per month. Find ratio of
(a) his income to his expenditure
Ratio of 1200:450 = 1200/450 = 8:3
(b) his savings to his income.
$1200 - $450 = $750 saving (assuming he saves the difference)
Ratio of 750:1200 = 750/1200 = 5:8
4. A car uses 40 lites of petrol to travel 340 km. how far can it travel if it has only 32 liters of petrol?
Set up a ratio,
340/40 = x/32
Cross multiply to solve
5. A pile of 108 identical book has a mass of 30 kg
a) The mass of 150 books
Set up a ratio,
108/30 = 150/x
Cross multiply to solve
(b) the number of books that has a mass of 20 kg
Set up a ratio,
108/30 = x/20
Cross multiply to solve
6. At scouts' camp there is sufficient food to last 72 scouts for 6 days if 18 scouts do not turn up for the camp, how much longer can the food last for the other scouts?
Set up a ratio,
72 - 18 = 54
72/6 = 54/x
Cross multiply to solve
