When the dimensions of the prism are doubled then the volume becomes eight times more of its original volume.
Explanation:
Given -
Length, L1 = 5cm
width, W1 = 4cm
height, H1 = 3cm
when the dimensions are doubled, the value becomes
Length, L2 = 2 X 5cm = 10cm
width, W2 = 2 X 4cm = 8cm
height, H2 = 2 X 3cm = 6cm
The volume of the initial prism = length X width X height
Volume 1 = 5cm X 4cm X 3cm
Volume 1 = 60cm³
The volume of the final prism = length X width X height
Volume 2 = 10cm X 8cm X 6cm
Volume 2 = 480cm³
Therefore, when the dimensions of the prism are doubled then the volume becomes eight times more of its original volume.
