Answer:
a. 30 cm³
b. 4.33 g/cm³
Explanation:
a Volume of the object = l*w*h
l = 5 cm
w = 2 cm
h = 3 cm
Volume of object = 5*2*3 = 30 cm³
b. Density of the object = mass of the object / its volume
Mass of object = 130 grams
Volume = 30 cm³
Density of the object = 
The answer is diphtheria. The symptoms of diphtheria usually track an incubation period of two to five days. Symptoms primarily are general and nonspecific frequently approaching a typical viral upper respiratory infection.
