Smaller cube (1 cm X 1 cm X 1 cm) 

<span>The surface area of one side = 1 cm X 1 cm = 1 <span>cm2</span></span>

 

<span>There are 6 sides, total SA = 6 X 1 <span>cm2</span> = 6 <span>cm2</span></span>

 

<span>Volume = 1 cm X 1 cm X 1 cm = 1 cubic cm (1 <span>cm3</span>)</span>

<span>Surface to Volume Ratio = 6 <span>cm2</span>/1 <span>cm3</span> = 6 <span>cm2/cm3</span></span>


Larger cube (6 cm X 6 cm X 6 cm) 

<span>The surface area of one side = 6 cm X 6 cm = 36 <span>cm2</span></span>

 

<span>There are 6 sides, the total SA = 6 X 36 <span>cm2</span> = 216 <span>cm2</span></span>

How are frogs adapted for terrestrial life?
shusha [124]
Frogs are amphibians, which means they need to live in both water and land.

They are adapted to hop on land with their feet, and their tongue to eat.

The reason frogs have lungs and also breathe through skin is so they can breathe in both of their habitats

Lunar Tides: the moon's gravitational pull on the Earth is strongest at this time, because it is closest, causing especially high and low tides.

Solar Tides: the sun's gravitational pull on the Earth is strongest at this time, causing especially high and low tides (although it's not as powerful as lunar tides).

Spring Tides: named for when the tides "spring" forward during New and Full Moon's, because of how strong/weak the moon's gravitational pull is.

Neap Tides: the tides are especially mediocre at this time, because the sun and moon are at a right angle and pulling in opposite directions.

Spring and Neap Tides occur twice every moon cycle, which lasts 28 days, so every two weeks.
