Step-by-step explanation:
the correct formula for this is the heron's formula
which states that s=√s(s-a)(s-b)(s-c). Where s is a+b+c all divided by 2
s=√(13.5-12)(13.5-9)(13.5-6)
s=√(1.5)(4.5)(7.5)
s=√50.625
s= 7.11 or 7 to the nearest square unit
X= 2(7/10)
X= 14/10
X= 7/5

The answer can be found by subtract the volume of the small box from the volume of big box.
Volume of the small box:
12*8*4= 384 inches cube
Volume of the big box:
20*15*9= 2700 inches cube
The space left:
2700 - 384 = 2316 inches cube
The speed of Maglev train is 267 miles per hour.
Step-by-step explanation:
Given,
Speed of Maglev train = 430 kilometers per hour
We know that;
1 kilometer = 0.62 miles
Therefore,
430 kilometers = 0.62*430
430 kilometers = 266.6 miles
Rounding off to nearest whole number
430 kilometers = 267 miles
The speed of Maglev train is 267 miles per hour.
