@Vivek3461 please help me my friend

OpenStudy (vivek3461):

Volume of water can be found by multiplying the Area of triangle formed by water at the sides and the length of the prism

OpenStudy (anonymous):

can you show me the solution, so that we can move on the other problems :D

OpenStudy (vivek3461):

Area of the wet part can be found by adding the areas of triangles and rectangles formed by the filled water.

OpenStudy (vivek3461):

Its very easy only. You try it out first. So i can help you where you find difficult. Else it would spoil the fun.

OpenStudy (anonymous):

FIRST STEP, WHAT CAN I SOLVE?

OpenStudy (vivek3461):

Find the area of the triangle formed by water at the end. Its height is 6. But base is unknown. So base can be found by using the bigger triangle's (actual container's triangle) height and base.

OpenStudy (anonymous):

1/2 bh A of triangle

OpenStudy (vivek3461):

The base of the smaller triangle can be found using proportionality. b1 / h1 = b2 / h2

OpenStudy (anonymous):

A= 3b

OpenStudy (anonymous):

the base of the bigger triangle is 8, i am right?

OpenStudy (vivek3461):

yes.. it is b1 and h1 = 12

OpenStudy (anonymous):

so the base is 4

OpenStudy (anonymous):

next step

OpenStudy (anonymous):

Area of the smaller triangle?

OpenStudy (vivek3461):

yes... proceed

OpenStudy (anonymous):

i got 12 inches^2
