martin is an artist who molds plaster into unique shapes.
how much plaster can martin fit into the mold shown?
a 66 ft³
b 60 ft³
c 128 ft³
d 256 ft³

Explanation:

Step1: Calculate volume of large cube

Volume formula: $V_1 = s_1^3$ where $s_1=4$ ft.
$V_1 = 4^3 = 64$ ft³

Step2: Calculate volume of small cube

Volume formula: $V_2 = s_2^3$ where $s_2=2$ ft.
$V_2 = 2^3 = 8$ ft³

Step3: Sum the two volumes

Total volume = $V_1 + V_2$
$64 + 8 = 72$ ft³

Step4: Match to correct option

The calculated total volume matches option A.

Answer:

A. $72\ ft^3$
