1. = Surface area
Volume
= (2 * 1) m²
(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
= (40 * 30)m²
(40*30*40) m³
= 0.025 m-1
4.
= S/V
= (4 * 6) cm²
(4*6*5) cm³
= 0.2 m-1
hope you understand. All the best!
