Answer:
P=10√2
Step-by-step explanation:
Perimeter of rectangle= 2 length + 2 width
P=2l+2w
P=2(√18)+2(√8)
P=2(√9*2)+2(√4*2)
P=2*3*√2 +2*2√2
P=6√2+4√2
P=10√2
Answer:
Volume of cube = 2.33 cubic feet
Length of side of cube = 1.325 feet
Step-by-step explanation:
Given
Weight of each sphere = 350 pounds
Density of each concrete = 150 pounds per cubic foot
Volume of cube = 350 pounds / 150 pounds per cubic foot
Volume of cube = 350/150 cubic feet
Volume of cube = 2.33 cubic feet
Length of side of cube = Cubic root of 2.33
Length of side of cube = 1.325 feet
