Answer:
20
Step-by-step explanation:
formula for triangle= 1/2*base*height
=1/2*8*5
=20
You can just multiply the area of the base times the height. The base is a triangle which has an area of bh/2. If we let b=base, h=height (of the triangle base) and H=the height of the prism, then:
V=Hhb/2, in this case:
V=17*2*1/2
V=17m^3

Answer:
12 x 3 = 36
Step-by-step explanation:
Your answer is 36
Formula of a parallelogram:
B x H = (BH)
Multiples of 3 plus 1 remainder are:
3n+1
Multiples of 4 plus 1 remainder are:
4n+1
Since these multiples must be the same number must be a multiple of 12 plus a remainder of one, which is:
12n+1
And the smallest such three digit number is:
12n+1>99 subtract 1 from both sides
12n>98 divide both sides by 12
n>8.17
Since n must be an integer, n=9
So then number is 12n+1
12(9)+1=109
