Hurry pls :/ calculate the volume of this shape.

1. 504cm3

2. 204cm3

3. 252cm3

4. 665cm3

250.55 cu. cm

Step-by-step explanation:

V=1/4h√﹣a^4+2(ab)^2+2(ac)^2﹣b4+2(bc)^2﹣c^4

=1/4x12x√-14^4+2·(14x14)^2+2·(14x3)^2﹣144+2·(14x3)^2﹣3^4

≈250.5494

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

the first one

step-by-step explanation:

just id the test.
