The walls are 9.7 feet wide and the tiles are 5 inches wide. Converted into centimetres the wall should be 295.65cm wide and tiles should be 12.7cm wide therefore, 295.65/12.7 = 23.27 tiles will be needed to fit the wall.
a. Surface area = 172 cm²
Volume = 112 cm²
b. The surface area would be needed.
c. The volume would be needed.
<h3>How to Find the Surface Area and Volume of a Box?</h3>
Surface area = 2(wl+hl+hw).
Volume = (length)(width)(height)
a. l = 7 cm
w = 2 cm
h = 8 cm
Surface area =2(wl+hl+hw) = 2·(2·7+8·7+8·2) = 172 cm²
Volume = (7)(2)(8) = 112 cm²
b. The surface area would be needed.
c. The volume would be needed to find the amount of juice the box will hold.

Answer:
Average speed v = 83.8 km/h
Step-by-step explanation:
Given;
Distance travelled = 95 km
Time taken t = 12.23 - 11.15 = 1 hour 8 minutes
t = 1 + 8/60 hours = 1.133 hours.
Average speed v = distance travelled/time taken
substituting the values;
v = 95 km ÷ 1.133 hours
Average speed v = 83.8 km/h
