what is the volume of a brick that is 2cm by 3.5cm by 8.15cm

57.05 cm³

Explanation: To find the volume of the brick, we use the formula for the volume of a rectangular prism.

Volume = length × width × height

Since the rectangular prism has a length of 2 centimeters, a width of 3.5 centimeters, and a height of 8.15 centimeters, we can plug this information into the formula.

Volume = (2 cm) (3.5 cm) (8.15 cm)

Volume = 57.05 cm³

Therefore, the volume of the brick is 57.05 cm³.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
