There are 36 unique quadrilaterals in a 3x3 square grid:
14 squares = 9 (1x1) 4 (2x2) 1 (3x3)
22 rectangles = 6 (1x2) 6 (2x1) 6 (3x3) 2 (2x3) 2 (3x2)
(the total number of quadrilaterals formed by 3 x 3 pin sets will be larger, i.e. 78)

How many boxes in a 3 x 3 grid?
There are 9 boxes in a 3x3 grid.
How many squares and rectangles are there in a 3 by 3 grid?
14
How many squares in a 3 by 4 grid?
12 squares.
How many sides do 3 dodecagons and 2 quadrilaterals have altogether?
A dodecagon has 12 sides, and a quadrilateral has 4 sides, so 3 dodecagons and 2 quadrilaterals have 3*12 + 2*4 = 36 + 8 = 44 sides altogether.
How many sides do 2 quadrilaterals and 3 pentagons have altogether?
A quadrilateral has four sides and a pentagon has five. So 2 quadrilaterals and 3 pentagons have 2x4 +3x5 sides = 8 + 15 = 23 sides altogether.
What shape does 3 congruent quadrilaterals make?
a big quadrilateral

How many triangles can you make on a 3X3 grid?
The correct answer is 76. There are 9 points in the grid. You can pick any 3 out of these 9 points in 9*8*7/(3*2*1) = 84 ways. However, 3 will form horizontal lines in the grid, 3 will form vertical lines in the grid, and 2 will form diagonal lines in the grid. None of these 8 triplets will form triangles, but all the rest will. So the answer is 84-8=76.

How many squares in a 3 by 4 grid?
12 squares.
How many squares are in a 3 by 2 grid?
Only 2.
How many sides do 1 heptagon and 3 quadrilaterals have altogether?
A heptagon has seven sides and a quadrilateral has four, so 1 heptagon and 3 quadrilaterals have 1*7 + 3*4 = 7 + 12 = 19 sides altogether.
