Answer:
1) X=12
Step-by-step explanation:
The triangle is congruent by SAS because one side is congruent, one is 90 degree that means other angle is also 90. Which is SAS, if the triangle is congruent then cpctc
The first thing we must do is find the volume of the rectangular prism which will be given by:
Vtotal = (20) * (2) * (3 1/4)
Votal = 130 in ^ 3
We now look for the volume of each individual cube:
Vcube = (1/4) ^ 3
Vcube = 1/64 in ^ 3
The number of cubes will be:
N = (Vtotal) / (Vcube)
N = (130) / (1/64)
N = 8320
Answer:
to fill the rectangle are needed 8320 cubes
Answer:
524cm^2
Step-by-step explanation:
Formula for Volume of sphere= 4/3 πr^2
We have,
r=5cm
Now,
Volume(v)=4/3 πr^2 = 4/3π 5^3= 4/3π 125 = 166.666666667π = 523.598775599
Rounding to the nearest tenth,
Volume=524cm^2
324 divided by 9 equals 36
