Answer:

Three cubes


Step-by-step explanation:


The cubes have to be indistinguishable and all orientations of one cube are also have to be indistinguishable.


All ways of connecting two cubes result in the same shape. So answer is larger than two.


After connecting two cubes, there are ten faces where the third cube can be attached, and two faces which are connected, accounting for all 12 faces of two cubes.


Of the 10 exposed faces, exactly two are on opposite ends, both leading to the same straight line figure. The other 8 faces all lead to an L shape, and all L shapes can be rotated to be identical.


Hence, three cubes can only make a straight shape or an angled shape.


Four cubes can make a straight shape, a L shape, a Γ shape (but flipping it over through 3 dimensions makes L and Γ identical), a T shape, and a square shape. That is either four or five different objects depending on if they can be lifted from the table. Anyway, it is more than two.

Answer:

x° = 139

step 1 :

180 - (37 + 38)

= 180 - 75

= 105°

step 2 :

180 - 105

= 75°

step 3 :

180 - 116

= 64°

step 4 : this step to find the value of x

x° = 180° - (64 + 75)°

= 180° - 139°

= 41

x° = 41

Jessica fills a cube shaped tank that has an edge of 70 cm with water from a tap. Water flows into the tank at a rate of 7L per
daser333 [38]

The volume of the tank is (70 cm)³ = 343,000 cm³.

Now,

1 mL = 1 cm³

1 L = 1000 mL

so we convert the given rate to

\dfrac{7\,\rm L}{1\,\rm min} \cdot \dfrac{1000\,\rm mL}{1\,\rm L} \cdot \dfrac{1\,\mathrm{cm}^3}{1\,\rm mL} = \dfrac{7000\,\mathrm{cm}^3}{1\,\rm min}

Then the time it will take to fill up the tank is

343,000\,\mathrm{cm}^3 \cdot \dfrac{1\,\rm min}{7000\,\mathrm{cm}^3} = \boxed{49\,\rm min}
