A right rectangular prism has length 3 and one third yd​, width 2 and one third yd​, and height 1 and one third yd. You use cube
Levart [38]

Answer:

Volume of the rectangular prism = 280 cubes

Volume of the rectangular prism = (280/27) yd³

Step-by-step explanation:

length 3 and one third yd​ = 3 + (1/3) yd = (10/3) yd

width 2 and one third yd​ = 2 + (1/3) yd = (7/3) yd

height 1 and one third yd = 1 + (1/3) yd = (4/3) yd

Cubes of edge length (1/3) yd are used to fill the rectangular prism.

The length would contain (10/3) ÷ (1/3) = 10

The width would contain (7/3) ÷ (1/3) = 7

The height would contain (4/3) ÷ (1/3) = 4

Volume of the rectangular prism = 10×7×4 = 280 cubes

Or

Volume of rectangular prism = (10/3)(7/3)(4/3) = (280/27) yd³

What is the solution to the following equation x+y=6 x-y=2
Lelechka [254]
X+y = 6
x-y = 2

Add both equations, 
2x = 8
x = 4

Substitute it in equation 1, 
4+y = 6
y = 6-4 = 2

In short, x = 4 & y = 2

Hope this helps!
