Answer:

400 cm²

Step-by-step explanation:

The new volume = 64,000 cm³

New length = (new volume)⅓ = (64,000)⅓ = 40cm

Old length = 40 cm ÷ 2 = 20 cm

Area = length² = 20² = 400 cm²

Answer:

400 cm²

Step-by-step explanation:

(side2/side1)³ = Volume2/Volume

2³ = 64000/X

X = 64000/8

X = 8000

Volume = side³

8000 = side³

Each side = 20

Area of a face = side²

= 20² = 400 cm²

help pleaseeeeee!!!!!!!!!! How many unit cubes would it take to completely fill the prism with no gaps between unit cubes?
vodka [1.7K]

Answer:

72

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
