The full length of the journey = 3150 miles
on the first day they completed = 567 miles
suppose 567 is x% of 3150 So
3150 x = 567
--------------
100
let us multiply both sides by 100 and divide both sides by 3150
x= 567 * 100
---------------
3150
x= 18
Answer is 18 %
To estimate the volume of Thai triangular prism you will use the formula for finding the volume.
V=Bh, where B is the area of the base and h is the height of the prism.
V = (1/2 x 12.6 x 1.6) x 10.75
V = 108.36 cubic mm
You answer is approximately 108 cubic millimeters.
