The daycare has two sandboxes that are both prisms with regular hexagons as bases. The smaller sandbox has a base area of 1,146 inches square and is filled 10 inches deep with sand. If it took 14 bags to fill up the sandbox 10 inches, what volume of sand comes in one bag?
In a Triangle AB=AC, <BAC=120°. D is the middle point of BC. O circle is drawn inside the triangle which touches AD,CD,& AC. If OA=4(meter) What's the radius of the circle???
The diagonals of the plane quadrilateral ABDC intersect at O and X,Y are the midpoints of the diagonals AB and BD respectively.show that BA+BC=2BX
and BA+BC+DA+DC=4YX
OABC is a tetrahedron andOA=a,OB=b and OC=c. The points P and Q are such that OA=AP and 2OB=BQ. The point M is the midpoint of PQ. Find (i) AB, (ii) PQ, (iii) CQ, (iv) QM, (v) MB and (vi) OM in terms of a, b and c.
ABCD is a plane quadrilateral and E is any point on AD. EF is drawn parallel to DB to meet AB in F and EG is drawn parallel to DC to meet AC in G. Prove that FG is parallel to BC.
