_______________________________________________________________

Answer:

Because in centimeters we measure smaller lengths and for

little larger lengths we measure with meter stick or meter tape

which is quicker,

Explanation:

I want to measure those five items with a

meter stick or meter tape instead of a centimeter ruler

because in centimeters we measure smaller lengths and

for little larger lengths we measure with meter stick or

meter tape as 1 meter = 100 centimeters.

Question 4.

The distance from the cafeteria to the gym is 14 meters.

The distance from the cafeteria to the playground is double

that distance. How many times would you need to use a meter

stick to measure the distance from the cafeteria to the playground?

Answer:

28 times I would need to use a meter stick to measure the

distance from the cafeteria to the playground,

Explanation:

Given the distance from the cafeteria to the gym is 14 meters.

The distance from the cafeteria to the playground is double

that distance. So number of times would I need to use a meter

stick to measure the distance from the cafeteria to the playground

is 14 + 14 = 28, therefore 28 times I would need to use a meter

stick to measure the distance from the cafeteria to the playground.

____________________________________________________________

____________________________________________________________

____________________________________________________________

Answer:

The length as per centimeter cube is

Triangle A is 27Â cm^{3} long,

Semicircle C is 125 cm^{3} long,

Rectangle E is 64 cm^{3} long,

Rhombus B is 27 cm^{3} long,

Hexagon D is 64 cm^{3} long,

Explanation:

The strategy to find the length of each shape

above is different from how I would find the length if you

used a centimeter cube is as aÂ cubic centimetre is a

commonly used unit of volume that corresponds to the volume

of a cube that measures 1 cm x 1 cm Ã— 1 cm. So length as per

centimeter cube is Triangle A is 27Â cm^{3} long,

Semicircle C is 125 cm^{3} long,

Rectangle E is 64 cm^{3} long,

Rhombus B is 27 cm^{3} long,

Hexagon D is 64 cm^{3} long respectively.
