Question

Martin is an artist who molds plaster into unique shapes. How much plaster can Martin fit into the mold shown? Cuboid with length as 1 ft, height as 2 ft and width as 1 ft. Is placed above the cuboid with length, height and width as 4 ft. A. 66 ft3 B. 80 ft3 C. 128 ft3 D. 256 ft3

Answer 1

Answer:

$Amount = 66ft^3$

Step-by-step explanation:

No attachment given, but the question can still be solved.

Given

Cuboid 1

$Length = 1ft$      $Width = 1ft$      $Height = 2ft$

Cuboid 2

$Length = Width = Height = 4ft$

Required

How much plaster can fit in

To do this, we simply calculate the volume of the shape

For cuboid 1

$Volume = Length * Width * Height$

$V_1 = 1 * 1 * 2$

$V_1 = 2ft^3$

For cuboid 2

$V_2 = 4 * 4 * 4$

$V_2 = 64ft^3$

Amount of plaster is then calculated as:

$Amount = V_1 + V_2$

$Amount = 2ft^3 + 64ft^3$

$Amount = 66ft^3$
