Volume of one pyramid = 408.6*(755.9*755.9)*1/3
volume of 3 pyramids= 3*408.6*(755.9*755.9)=700,403,500.11*1/3=233,467,833.37
reasoning 3 square base pyramid = 1 cuboid
Answer:
4cm^2
Step-by-step explanation:
First we need to find the length of the height of the triangle using Pythagoras:
a^2+b^2=c^2 (Substitute in what we have)
a^2+3√2(^2)=2√5(^2) = a^2 + 18 = 20 -> 20-18=2 √2=BD
Now we can find the area:
AD+DC= 3√2 + √2 = 4√2 x √2 = 8/2 = 4
58^(1/2) is √58 if that is what you meant
