Answer:
There are 28,000 sweat glands on a hand measuring 7 cm by 8 cm.
Step-by-step explanation:
We assume the palm has the shape of a rectangle.
The area of a rectangle is length × width.
The area of a palm measuring 7 cm by 8 cm is:
length × width = 7 cm × 8 cm = 56 cm²
Since 1 cm² has 500 sweat glands, 56 cm² has 56 times as many sweat glands.
500 × 56 = 28,000
Answer: There are 28,000 sweat glands on a hand measuring 7 cm by 8 cm.
