Answer:
0.001953125
Step-by-step explanation:
Divide 34 by 512
34 ÷ 512 = 0.06640625
divide 0.06640625 by 34
0.06640625 ÷ 34 = 0.001953125
Check you work
34 × 0.001953125 = 0.06640625
Answer is 3 4 ÷ 5 12 = 3 4 × 0.001953125
Let
b-----------> the length side of the square box
h------------> the height of the box
SA---------> surface area of the box
we know that
[volume of the box]=b²*h
volume=256 in³
b²*h=256-------> h=256/b²-----> equation 1
surface area of the box=area of the base+perimeter of base*height
area of the base=b²
perimeter of the base=4*b
surface area=b²+(4*b)*h------> SA=b²+4*b*h-----> equation 2
substitute equation 1 in equation 2
SA=b²+4*b*[256/b²]-----> SA=b²+1024/b-----> SA=(b³+1024)/b
the answer is
the formula of the volume of the box is V=b²*h-----> 256=b²*h
the formula of the surface area of the box are
SA=b²+4*b*h
SA=(b³+1024)/b
The answer is 3 for this question.
42 - -84=-42
