What is the surface area of the given figure?
*Picture of Triangular Prism*
My work:
2 Triangles
3 Rectangles
SA= sum of all areas of all faces
A=1/2bh
A=1/2(260)
A=130
Both Triangles=130+130
Both Triangles Together:260
A=lw
A=36*28
A=1,008
A=lw
A=36*26
A=936
A=lw
A=36*10
A=360
260+1,008+936+360=2564 cm^2
a. 2564 cm^2 <<
b. 2276 cm^2
c. 2184 cm^2
d. 1160 cm^2
Use the net to find the approximate surface area of the cylinder to the nearest square meter.

My Work:
2 circles
1 rectangle
SA=2πr^2 + πdh
SA=2(3.14)(5)^2+(3.14)(10)(9)
SA=2(3.14)(25)+(3.14)(10)(9)
2(78.5)+282.6
157+282.6
439.6
Rounded: 440m^2
a. 440 m^2 <<
b. 314 m^2
c. 283 m^2
d. 214 m^2

V=Bh
V=(1/2bh)(18)
V=(12)(18)
V=216 ft^3
a. 864 ft^3
b. 432 ft^3
c. 216 ft^3 <<
d. 492 ft^3
What is the volume of the cone to the nearest whole unit?
My Work:
V=1/3πr^2h
V=1/3(3.14)(4)^2(9)
V=1/3(3.14)(16)(9)
V=1/3(452.16)
V=150.72 in^3
Rounded: 151 in^3
