y^8 = 4
y^7 = 3/x

y(y^7) = 3/x(y)
y^8 = 3y/x

3y/x = 4
3y = 4x
y = 4x/3

Answer: (A)

vodka [1.7K]

Answer:

Step-by-step explanation:

As you can see the top - view is a rectangle of 2 by 9 dimensions. Respectively the right - side view is a rectangle of 2 by 4 dimensions. The common dimension among both rectangles would be 2, making this rectangular prism have dimensions 2 by 4 by 9.

Therefore the rectangular prism will have a volume of 2 $*$ 4 $*$ 9

2 $*$ 4 $*$ 9 = 8( 9 ) = 72 cubic units

Solution : 72 unit cubes
