Answer:
Rectangular prism
I chose a box of cereal.
Part 1)List the dimensions of your box. Be sure to include the units (in, cm, ft, etc.).
Length: 20 cm
Width: 8 cm
Height: 32 cm
Part 2).
Describe the shape of the cross-section when the box is cut parallel to the base.
The shape of the cross-section would be a rectangle in dimensions.
20 cm x 8 cm
Part 3)
What is the surface area of the box?
surface area=2*area of the base + perimeter of the base*height
area of the base=20*8=160 cm²
perimeter of the base=2*[20+8]-----> 56 cm
height=32 cm
surface area=2*160+56*32------> 2,112 cm²
the answer part 3) is
2,112 cm²
Part 4)
What is the surface area of the box if it is scaled up by a factor of 10?
we know that
surface area of the larger box =[scale factor]²*surface area original box
scale factor=10
surface area original box=2,112 cm²
so
surface area of the larger box=10²*2,112-----> 211,200 cm²
the answer part 4) is
211,200 cm²
Part 5)
What is the volume of the box?
volume of the box = L*W*H 20*8*32-5,120 cm³
the answer Part 5) is
5,120 cm³
Part 6)
What is the volume of the box if it is scaled down by a factor of 1/10?
we know that
the volume of the smaller box =[scale factor]³volume original box
scale factor=1/10
volume original box=5,120 cm³
so
volume of the smaller box =[1/10]³*5,120 5.12 cm³
the answer part 6) is
5.12 cm³
The length is 6 in., the width is 2 in., and the height is 16 in.
y = 3x – 8
y = -x – 4
Answer:
slope is 3 and -1
Step-by-step explanation:
Answer:https: y+3x-8
Step-by-step explanation: first: put your first point at -8
second: then from the point at -8, go up three times, and over to your right one time
now do that however many times you need to
explanation:
- the y-intercept is the initial value which is -8. the line must pass through -8 so you would start your line at -8
- your slope is 3x. slope is so you rise 3 time and over 1 time
y = -x – 4 -4.0
y-intercept = -4/1 = -4.00000
6 pencils are in 1 pack. & 18 pencils are in 3 packs.
Division is the process of splitting a number or an amount into equal parts.
Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.
here, we have,
There are 36 pencils in 6 packs.
Igor wants to know how many pencils are in 1 pack.
i.e. we have to 36/6
=6
Elsa wants to know how many pencils are in 3 packs.
i.e. we have to 3*6
=18
Hence, 6 pencils are in 1 pack. & 18 pencils are in 3 packs.
