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!

Required area = lb + 2 × h ( l + b)
= 4 × 3 + 2 × 7 (4 + 3)
= 12 + 14 × 7 = 12 + 98 = 110 m²
Cost of white-washing at the rate of $6/m²
= $ 110 × 6 = $ 660
Answer: v = 25
Step-by-step explanation:
Divide each side by 3
3v/3 = v
75/3 = 25
v = 25
25 * 3 = 75
1.76
Subtract 2.5 to 3/4 by dividing 3 to 4 getting the answer of 1.76
2/9 Is your simplified fraction! Have a great day!
