Answer:
81 cubes are needed to fill the prism
Step-by-step explanation:
Volume of prism = 3 cubic units
Side lengths of cube = 1/3
Therefore the volume of the cube is,
V = a³ (a = side of the cube)
V = 1/3 × 1/3 × 1/3
= ( 1/3 )³
= 1/27 cubic units
To find the number of cubes needed to fill the prism, we need to divide the volume of cube by volume of the prism.
Number of cubes to fill the prism= Volume of prism / Volume of cube
= 3÷1/27
=3×27/1
= 81
Therefore, 81 cubes are needed to fill the prism.
Answer:
10n+3
Step-by-step explanation:
-n+12n+3-n
-n+12n-n+3
11n-n+3
10n+3
6^=3 = 1/6^3 = 1/216
2^-2 = 1/4
1/3^2 = 1/9 = 3^-2
K equals 360
50 x 7.2 =360
360/7.2 = 50
