Answer:
Volume: 2000 cm^3 Surface Area: 1360cm^2
Step-by-step explanation:
Ok, so we know the formula for volume is length x width x height, so we can substitute in the numbers given, so we end up with:
25 x 4 x 20
when we multiply them together, we get:
2000cm^3. That's the volume.
The formula for Surface Area is:
S.A.=2(lw+wh+lh) . Now we substitute in the numbers given
S.A.=2( (25 x 4)+(4 x 20)+(25 x 20)) . Then we add and multiply, so we get:
S.A. = 1360cm^2
The Surface Area is 1360cm^2.
Hope this helped, sorry if I was wrong somewhere!

So, the question is 63 is 30% of what number?
That can translate to the equation
63 = 30% · x or 63 = 0.3x
Divide by 0.3 and you get x = 210.
