The faces of a cube have an area of 0.01 square units each. What is the cube's volume? cubic units

0.006 cubic units

Step-by-step explanation:

Area of each face of cube

= 0.01 square units

No. of faces of cube

= 6

Total surface area

= 6×0.01

= 0.06 square units

Volume

= 6×a³

= 6×a²×a

= 6×0.01×√0.01

= 0.006 cubic units

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
