3.0 cm x 4.0 cm x 1.0 cm

[?]cm^3

Explanation:

Hi there!!

you asked to multiply these all right,

you can simply multiply it ,

=3cm × 4 cm × 1cm

= 12cm^2×1cm(4×3=12)

= 12cm^3(12×1=12)

Therefore, theanswer is 12 cm^3.

Hope it helps..

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
