Question 2
What is this shape?
Triangular prism
If you cut it anywhere, parallel to the front triangle side. What will be the shape of the cross section?
A triangle
What is the area of the front triangle? (Show working)
6.4*8.2 = 52.48 . As we are finding the area of a triangle we do the formula L*W/2. 52.48/2 = 26.24cm^2
If this was made of mm^3 blocks (some would need to be cut up) How many cubes would be needed to cover the front face?
???
How many rows of block triangles would you need to make the whole shape?
15.7
What is the volume of this shape? (Show working)
Formula = (L*H)/2*W
(8.2*6.4)/2=26.24cm^2
26.24*15.7= 411.968cm^2
I don't get the 'mm/cm^3' bit...
