Answer:
#1 1/4
#2. 8/27
#3 3/4
Step-by-step explanation:
let the side of the square be y
Area of a square = y x y = y^2
y^2 = 1/16
y = sqrt (1/16)
y = 1/4
volume of a cube = edge length x edge length x edge length
Volume of a cube = 2/3 * 2/3 * 2/3
Volume of a cube = 8/27
volume of a cube = (edge length)^3
Edge length = cube root (volume of a cube)
Edge length = cube root (27/64)
Edge length = 3/4
