The simplified version is 1 5/22
Answer:
The volume is 343 cubic feet
Step-by-step explanation:
∵The volume of the prism = area of the base × height
∵In the cube all faces are square with side length L
∴The volume of the cube = L × L × L
∴ V = 7 × 7 × 7 = 343 cubic feet
Period of cos(Bx) is 2pi/B
first case, B = 1
Second case, B = 2
so period of 5*cos x is 2pi/1 = 2pi
period of cos 5x is 2pi/5
hope this help
