Given:
A right rectangular prism is packed with cubes of side length
inch.
Prism is packed with 15 cubes along the length, 6 cubes along the width, and 5 cubes along the height.
To find:
The volume of the prism
Solution:
Side length of each cube
inch.
15 cubes along the length, so length of prism is

6 cubes along the width, so width of prism is

5 cubes along the height, so height of prism is

Now,
Volume of rectangular prism is





Therefore, the correct option is B.
Answer:
the answer is 0,3
Step-by-step explanation:
Answer:
x1 = 1 x2= 1/2
Step-by-step explanation:
DELTA= b^2-4*a*c
DELTA=(-6)^2-4*4*2= 4 >0 ==> 2 solutions
x1 = (-b+sqrtDELTA)/2*a = (6+2)/2*4 = 1
x2 = (-b-sqrtDELTA)/2*a = (6-2)/2*4 = 1/2
