How many cubic blocks with a side length of 1/8 inch are needed to fill a rectangular prism with a length, width, and height of 3/4 inch 1/2 inch, and 1/2 inch, respectively?

volume of cube is V=S^3

so 1/8 = 0.125 = 0.125^3 = 0.00195 in^3

volume of rectangle

V= l x w x h = 0.75*0.5*0.5 = 0.1875 in^3

0.1875/0.00195 = 96.15 round to 96 blocks

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )
