Answer:
The area of the speed-time graph gives us the distance travelled . In this case we drop a perpendicular from v=4 to t=2 . Hence, we get a rectangle and a triangle. Now we calculate the areas of the rectangle and the triangle. Rectangle = 2×4=8 m and triangle =1/2×(4–2)×4=4 m. Now to get the distance travelled we add the two up. Hence, distance travelled= (8+4)m =12 m.
Answer: The front face has an area of 30 ft2. , The top face has an area of 40 ft2. ,
Step-by-step explanation: SOrry if im wrong
S = edge length
Vol = s^3 = 216
There are 6 faces, each has an area of s^2
