Question

The net of a composite space figure is shown below.
a. What figures make up the composite space figure?
b. What is the surface area of the composite space figure? Round your answer to the nearest square centimeter

Answer 1

a) we have triangles, rectangles, and a hexagon. They would fold up and glue together to form a pencil shape. It's not 100% a pencil, but a bit close

b) find the area of each triangle, each rectangle, and the hexagon. Then add up the individual areas.

Answer 2

@mathmate @MrNood can yall please help me

Answer 3

You are not asked to name it or make it - (it doesn't have a technical name - piencil is a good description)

Have a look at the 'unfolded' net

You WILL recognise 3 different shapes that you CAN name

there are
6 type 2
6 type 1
1 type 3

find the name and the formula for area of each of thaose 3 shapes, then work out the are of each face type from those formulas

Answer 4

So when its asking for What figures make up the composite space figure? it mean triangle, hexagon and rectangle? is that correct or no.

Answer 5

yes

Answer 6

would ypu need the surface area or the area formula

Answer 7

The total area of the 'pencil' is made up of the area of the 13 other shapes.

You need to work out the area of each of the 3 different shapes and add up the sum for 13 total faces.

I don't know what you mean in your question - surface area , and area are the same afaik

Answer 8

triangle
A =1/2bh
S.A = L.A +2b
whick formula would i use

Answer 9

you have confused 2 separate options.

This is not a prism

find the area of a triangle and use that formula

Answer 10

a=1/2(4)(5)
a=1/2(20)
a=10

Answer 11

10 x 6 = 60 area of all 6 triangles

Answer 12

a=l*w
a= 6*4
a=24
24*6= 144 area of all the rectangles

Answer 13

how would i find the area of the hexagon

Answer 14

type the below into google:

"how would i find the area of the hexagon"

Answer 15

or split it into 6 equilateral triangles (but it will be the same equation in the end...)

Answer 16

Answer 17

a= 3sqrt3/2(4)^2
a= 3sqrt3/2(16)
a=41.57

Answer 18

1. A) The figures in the composition space figure are rectangles, triangles and a hexagon.

B) 1 hexagon =
a= 3sqrt3/2(4)^2
a= 3sqrt3/2(16)
a=41.57 cm.

6 triangles = a=1/2(4)(5)
a=1/2(20)
a=10 cm.
= 10 x 6
= 60 cm.
60 cm. is the area of all 6 triangles.

6 rectangles =
a=l*w
a= 6*4
a=24 cm.
a = 24*6
= 144 cm.
144 cm. is the area of all the rectangles.

Answer 19

what do i do after i find the area @phi

Answer 20

You add up all the areas to get the total surface area of the shape.

Answer 21

144+60 +41.57
S.A =245.57 cm.

Answer 22

yes. and they want you to round the answer to the nearest whole number.
can you do that ?

also, the units are cm^2 or "square cm" (not just cm)

Answer 23

246 cm^2 correct

Answer 24

yes, looks good.

Answer 25

thanks
