What size that barrel?
A standard oil barrel is defined as 42 US gallons. This equates to 231 cubic inches.
Given that 1 inch = 0.0254 m this implies that a barrel is 0.159 cubic metres.
A standard oil barrel is approximately 0.9 m high, what is the circumference?
Scalextric models are made to a scale of 1:32.
In the picture the oil barrels are actually 26mm tall, assuming the barrels are in proportion what is the scale of the barrels? If the barrels were to a true scale of 1:32 what would be their dimensions?
