Question

Find H. V = 768 cm3

Answer 1

Volume = areaBase *h
h = areaBase/volume
volume = 768
we need to find areaBase
for this figure the base or top and bottom is a right triangle
the triangle has one side of 8 and diagonal side of 17
area of triangle = 1/2*length*height
find height of triangle using pythagorean theorem
a^2 +b^2 = c^2
so 8^2+b^2 = 17^2
find b, then use that to find area of triangle

Answer 2

i got 15

Answer 3

correct
areaTriangle = 1/2*8*15

Answer 4

does 15 as height?

Answer 5

oops i made a mistake
h=volume/areaBase

Answer 6

yes 15 is height of triangle

Answer 7

Find h. V = 896 cm3

Answer 8

what do you get for an answer for H?

Answer 9

192

Answer 10

how did you get 192?

Answer 11

768=1/2*8*H

Answer 12

be careful there are 2 equations
one is for 2-dimensional triangle (The base)
one is for 3-dimensional prism
768 = (AreaTriangle)*H
AreaTriangle = 1/2*8*15

Answer 13

i got 12.8

Answer 14

correct

Answer 15

ok can u help me with the next question

Answer 16

Volume = areaBase*Height
896 = areaBase*24
areaBase = 896/24=112/3
Base is a hexagon, but can be split up into 2 trapezoids
Area of trapezoid = 1/2*h*(b1+b2) = 112/3
b1 =12
b2 = 20
solve for h

Answer 17

wait another mistake
areaTrapezoid = 1/2*areabase = 1/2*112/3 = 112/6=56/3

Answer 18

sorry i gotta go
good luck
