Answer and working out attached below. Hope it helps
Answer:
<h3><em>2cm</em></h3>
Step-by-step explanation:
Step one:
given data
for the large cube
the volume= 125cm^3
we know that volume = l*l*l
volume=l^3
we want to find l, so we have to cube both sides
125=l^3
l=∛125
l=5cm
Step two:
given data
for the large cube
the volume= 27cm^3
we know that volume = l*l*l
volume=l^3
we want to find l, so we have to cube both sides
27=l^3
l=∛27
l=3cm

Answer:
f(4) = -1

= 3*16 - 40 - 9
= 48 - 40 - 9
= -1
