Final answer:
Without the length and width of the agar block, the volume cannot be calculated with only the provided height of 30 cm. For a block with known dimensions (e.g., 2.1 cm x 34.0 cm x 118 cm), you multiply these values to get the volume in cubic centimeters and then convert to cubic meters if necessary.
Step-by-step explanation:
To calculate the volume of an agar block or any rectangular solid, you need to know the length, width, and height of the block and use the formula for volume: V = length × width × height. However, with only the height provided (30 cm), it's impossible to determine the volume without knowing the other dimensions. If you have the missing dimensions, simply multiply them with the height to get the volume.
For example, if an agar block's dimensions are given as 2.1 cm × 34.0 cm × 118 cm, then the volume is calculated as follows:
V = 2.1 cm × 34.0 cm × 118 cm = 8463.6 cm³
To express this in cubic meters (m³), you would convert the centimeters to meters. Since 1 cm³ is equal to 1×10⁻¶ m³:
V = 8463.6 cm³ × (1 m³/1×10⁻¶ cm³) ≈ 0.0084636 m³
