Answer:
1/2(1,080)cm^3
Explanation:
Height=10
Length=12
Width=9
Volume of a prism=1/2×l×h×w
Volume=Area of base×h
Area of base=1/2×l×w
=1/2×9cm×12cm
=1/2×108
=54cm^2
Volume=Area of base×h
=54cm^2 × 10cm
=540cm^3
Alternatively,
Volume of a prism=1/2×l×h×w
=1/2×12cm×10cm×9cm
=1/2×1080cm^3
The closest to the options provided is 1/2 of 1080 cm^3 using the given dimensions 10,9 and 12 for height, width and length respectively.
