Answer:

Step-by-step explanation:

Answer:
-6
Step-by-step explanation:
2(-1)^2 + 8*-1 = 2*1+8*-1=2-8=-6
The volume in cubic meter of the cuboid with the dimensions length = 12 m , breadth = 10m, height = 4.5 m is 540 m³
<h3 />
<h3>Volume of a cuboid:</h3>
where
l =- length
w = width
h = height
Therefore,
l = 12 m
w = 10 m
h = 4.5
v = 12 × 10 × 4.5
v = 120 × 4.5
v = 540 m³
