Here we have to know the conversion between feet and inches.
1 Feet = 12 inches (This is given and is to be known)
So the 5 feet wide footbridge when converted to inches would be about 5*12 = 60 inches
The width of the footbridge in inches = 60 inches
Each wooden plank is 6 inches,
So the number of wooden planks that are required to build the foot bridge of 60 inches = 60/6 = 10 planks
Hence, the path path is 10 planks wide
Answer:
the last one
Step-by-step explanation:
Volume of a cube is a side length cubed
So 7*7*7
Answer is 343 centimeters
Answer:
Variable = x
Coefficient = 2
Constant = 7
