We have 2 solid figures here and their volume = length*width * height,
So we find the volume of each solid then add them up.
Volume = length*width*height.
Take the small one first
length = 15, width = 14 and height = 16
so its volume is 14*15*16 = 3360
Large solid:
Note that its length = 15 + 16 = 31
its volume = 31*30*27 = 25,110
So the volume of the whole figure = 25,110 + 3360 = 28,470 (answer).
Formula of Area of triangle.... A=1/2bh where A is area, b is the base, and h is height.
h= 3b-1
Area=12
At this point you want to plug in what you know into the equation.
12=1/2b(3b-1)
Then you can solve for b. First multiply each side by 2 to cancel the fraction.
24=b(3b-1)
Then distribute the b term.
24=3b^2 - b
Then set the equation equal to zero.
0=3b^2-b-24
Then either factor or use the quadratic equation to solve for b.
0=(3b-8)(b-3)
which means that b=3 and b=8/3
You then plug both answers back into the original equation (12=1/2b(3b-1))and see if there are any extraneous solutions. When you do, you can see that 8/3 as an answer does not equal 12. Therefore, the correct answer and the base of the triangle is equal to 3.
Answer:
Length of Sofa: 6ft / Height of scale model: 15in
Step-by-step explanation:
Sofa:
1 inch = 1 foot
6 inches * 1 foot = 6 feet
Scale Model:
60 feet to a 4 inch scale
60 feet / 4 inches = 15 inches (aka 60 feet)
