1. = <u>Surface</u><u> </u><u>area</u>
Volume
= <u>(</u><u>2</u><u> </u><u>*</u><u> </u><u>1</u><u>)</u><u> </u><u>m</u><u>²</u>
(1*2*0.5) m³
= 2 m-1 (the negative 1 is an exponent).
2. for elephant,
= S/V
= 25/10
= 2.5 m-1
for pigeon,
= S/V
= 0.5/0.05
= 10 m-1
Pigeon has the larger surface area to volume ratio.
3.
= S/V
= <u>(</u><u>4</u><u>0</u><u> </u><u>*</u><u> </u><u>3</u><u>0</u><u>)</u><u>m</u><u>²</u><u> </u><u> </u><u> </u><u> </u>
(40*30*40) m³
= 0.025 m-1
4.
= S/V
= <u>(</u><u>4</u><u> </u><u>*</u><u> </u><u>6</u><u>)</u><u> </u><u>c</u><u>m</u><u>²</u>
(4*6*5) cm³
= 0.2 m-1
hope you understand. All the best!
