We look for the dimensions of the first rectangle:
 For the length:
 (2/6) L = 180
 L = (6/2) * (180)
 L = 540
 For the width:
 (3/5) W = 90
 W = (5/3) * (90)
 W = 150
 We look for the dimensions of the new rectangle:
 For the length:
 L '= 540-150
 L '= 390
 For the width:
 W '= (1/3) * (390)
 W '= 130
 Answer:
 The dimensions of the new rectangle are:
 L '= 390
 
W '= 130

a rectangular prism is 5 meters long, 17 meters wide, and 4 meters high. what is the surface area of the rectangular prism?
Mars2501 [29]

The surface area of rectangular prism is 346 square meters.

Given the figure is rectangular prism.

We know that the surface area of rectangular prism with length L, width W and height H is = 2(LW+WH+LH)

Given that the length of prism = 5 m

Width of prism = 17 m

Height of prism = 4 m

So the total surface area of the rectangular prism is given by,

= 2 [5*17 + 17*4 + 4*5]

= 2 [85 + 68 + 20]

= 2*173

= 346 square meters

Hence the surface area of rectangular prism is 346 square meters.
