A block of wood has a mass of 180 grams. It is 10cm long 6cm wide and 4cm thick. What is its volume and density?

1 answer:

8 0

Volume = (length) x (width) x (height) =

(10cm) x (6cm) x (4cm) = 240 cm³

Density = (mass) / (volume) = (180 g) / (240 cm³) = 0.75 gm/cm³ .

Susan completed a 26-mile rollerblade marathon in 2.5 hours. If Susan skated at a constant rate, how fast was she skating? A. 10

Bond [772]

Answer:

A. 10.4 mph

Step-by-step explanation:

26÷2.5=10.4

Double checking your answer:

If she does 10.4 miles in an hour, she can get 20.8 in two hours

then you add half of how much she can go in an hour which is 5.2 (10.4÷2)

you add it together, and you will get 26 miles in total

(20.8+5.2=26)
