1 answer:
Answer:
Volume of sculpture = 480 inch³
Step-by-step explanation:
Divided given sculpture into three cuboid.
Given:
Length of first cuboid = 4 inch
Width of first cuboid = 4 inch
Height of first cuboid = 4 inch
Length of second cuboid = 4 inch
Width of second cuboid = 4 inch
Height of second cuboid = 4 + 4 inch
Length of third cuboid = 4 inch
Width of third cuboid = 4 inch
Height of third cuboid = 4 + 4 inch
Computation:
Volume of cuboid = (l)(b)(h)
Volume of sculpture = (4)(4)(5) + (4)(4+4)(5) + (4)(4+4+4)(5)
Volume of sculpture = (4)(4)(5) + (4)(8)(5) + (4)(12)(5)
Volume of sculpture = 80 + 160 + 240
Volume of sculpture = 480 inch³
