A shipping box has the dimensions shown what is the volume of the box in cubic yards? 1-4 yard 1-4 yard 1-2 yard

andriy [413]

The required picture is attached below :

Answer:

1 /32 yard³

Step-by-step explanation:

The volume of box can be obtained using the relation :

V = length * width * height

Length = 1/4 yards

Width = 1/2 yards

Height = 1/4 yards

Hence,

Volume (V) = 1/4 yards * 1/2 yards * 1/4 yards

Volume (V) = (1/4 * 1/2 * 1/4)(yard³)

Volume (V) = 1 / 32 yard³
