The volume of a cuboid is 130cm square. If the solid is 7cm long and 5cm wide, calculate the height
first, volume is cm^3, not cm^2
7*5*h = 130
h = 130/35 = 26/7
hmmm. Maybe you meant the area is 130 cm^2. In that case,
2(7*5 + 7h + 5h) = 130
35 + 12h = 65
h = 30/12 = 5/2

To calculate the height of the cuboid, we can use the formula for the volume of a cuboid, which is:
Volume = length × width × height
In this case, the given volume is 130 cm³, the length is 7 cm, and the width is 5 cm.
We can rearrange the formula to solve for the height:
height = volume / (length × width)
Plugging in the values, we have:
height = 130 cm³ / (7 cm × 5 cm)
Now, let's calculate it step by step:
1. Multiply the length and width: 7 cm × 5 cm = 35 cm²
(Note: 1 cm² represents the area as volume is given in cm³.)
2. Divide the volume by the product of length and width: 130 cm³ / 35 cm²
3. Simplify the calculation: 130 cm³ / 35 cm² ≈ 3.714 cm
Therefore, the height of the cuboid is approximately 3.714 cm.
