Answer:
21.01 cubic metres
Step-by-step explanation:
We have to find the value of 1 cubic foot and then convert to cubic metre.
1 foot = 0.3048 m
1 cubic foot = = 0.02832 cubic metre
A volume of 742 cubic foot will therefore be:
742 * 0.02832 = 21.01 cubic metres
The volume in cubic metres is 21.01 cubic metres
Answer:
8 vans
7 buses
Step-by-step explanation:
Let there be "b" buses
and "v" vans
Since 7 people is the capacity of vans, the total capacity is
7v
Also, since 25 people is the capacity of 1 bus, the total capacity is
25b
In total 231 people, so we can write our first equation as:
7v + 25b = 231
Now, we know there are 15 vehicles (bus + vans) in total, so we can write our 2nd equation as:
v + b = 15
Now, we solve for v and b. Let's solve the 2nd equation for v and substitute that into 1st and solve for b first:
v + b = 15
v = 15 - b
Now,
Hence, there are 7 buses
Since 15 vehicles in total, the number of vans is:
15 - 7 = 8 vans
So,
8 vans
7 buses
