Can someone me with solving volume equations?

For 2, 30 cubic m., For 3, 90 cubic cm., For 4, 1000 cubic yards, for 5, 27 cubic mm., For 6, 120 cubic in.

Step-by-step explanation:

You can simply multiply all 3 sides to get the cubic volume B x h is the same as l x w x h

ex. Number 2, length 3, width 2, height 5

Base is 2x3=6 times 5 = 30 or 2 x 3 x 5=30

the forst and 3rd

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
