Answer:

i am so sorry if its wrong

Each of the triangles making up the sides and base have a base of 8 cm and a height of 6.9 cm. Then the area of the pyramid is that of 4 such triangles.

 A = 4×(1/2)×b×h

 A = 2×(8 cm)×(6.9 cm)

 A = 110.4 cm²Step-by-step explanation:

Which expression is a perfect cube?<br> 12x12y18<br> O 12x27,125<br> O 64x15y18<br> 64x27<br> 27,125
Dmitrij [34]

Answer:

D: 64 x^27 y^125

Step-by-step explanation:

You can use either a calc or your knowledge of cube roots. I will be using knowledge.

You can automatically <em>rule out</em> a and b as if you take the cube root of 12, no whole number comes out. You are left with c and d. Option D is correct because the cube root of 64 is a whole number (4), the cube root of 27 is a whole number (3), and the cube root of 125 is also a whole number(5).
