Answer: x = 1/2
Step-by-step explanation:
Volume of rectangular prism = length * width * height
Volume of triangular prism =( length * height * base )/2
Given,
Volume of rectangular prism = 18 + volume of triangular prism
18x = 18+14x
4x=18
x= 4.5 ft
So volume of rectangular prism = 6* 4.5* 3 = 81 ft³
Volume of triangular prism = (7* 4.5 * 4) / 2 = 63 ft³
Answer:
480
Step-by-step explanation:
If you take length times width times height so it'll be 8 times 10 = 80 times 6 =480
H. 135 meters
Work: 45 meters in 30 seconds 45/30= 1.5 so 90x1.5 = 135 meters
