Answer:
Hundreds
Step-by-step explanation:
I'm assuming you mean place value
All faces are rectangles.
Each two opposite faces are congruent and have the same area.
Two faces measure 20 cm by 7 cm.
Two faces measure 20 cm by 15 cm.
Two faces measure 15 cm by 7 cm.
total surface area = 2 * 20 cm * 7 cm + 2 * 20 cm * 15 cm + 2 * 15 cm * 7 cm
total surface area = 280 cm^2 + 600 cm^2 + 210 cm^2
total surface area = 1090 cm^2
50.24 bc a=3.14(radius to second power) and the radius would be 4, 4•4=16 and 16•3.14=50.24
Answer:
Step-by-step explanation:
Back
Area = L * W
L = 20
W = 8
Area = 20 * 8
Area = 160
2 Triangles
Area = 1/2 one smaller leg*other smaller leg
one smaller leg = 8
The other one = 15
Area = 1/2 8 * 15 = 60
But there are 2 of them 2 * 60 = 120
Base
L = 20
W = 15
Area = L * W
Area = 20*15 = 300
Front (slanted) Face
L = 20
W = 17
Area = L * W
Area = 20*17 <u> 340</u>
Total 920
