1) the volume of a rectangular prism that has a length of 3 units, a width of 6 units, and a height of 4 units is found by v=lwh=(3)(6)(4)=72 and a) v=(2b)(h) b) v=(b)(2h) c) v=bh d) v=1 2 bh 2) the volume of a rectangular prism that has a length of 5 units, a width of 2 units, and a height of 3 units is found by v=lwh=(5)(2)(3)=30 and a) v=(2b)(h) b) v=(b)(2h) c) v=bh d) v=1 2 bh 3) the volume of a rectangular prism that has a length of 5 units, a width of 3 units, and a height of 3 units is found by v=bh=(15)(3)=45 and a) v=(2lw)(h) b) v=2lwh c) v=lwh d) v=1 2 lwh 4) the volume of a rectangular prism that has a length of 5 units, a width of 5 units, and a height of 7 units is found by v=bh=(25)(7)=175 and a) v=(2lw)(h) b) v=2lwh c) v=lwh d) v=1 2 lwh

Part 1) we know that
Volume of rectangular prism=L*W*H> 3*6*4> 72 units ³
and 
Volume of rectangular prism=Area of the base*H
Area of the base B=L*W> 3*6> 18 units²
so
Volume of rectangular prism=18*4> 72 units³

the answer Part 1) is the option
 C) V=Bh

Part 2) we know that
Volume of rectangular prism=L*W*H> 5*2*3> 30 units ³
and 
Volume of rectangular prism=Area of the base*H
Area of the base B=L*W> 5*2> 10 units²
so
Volume of rectangular prism=10*3> 30 units³

the answer Part 2) is the option
 C) V=Bh

Part 3) we know that
Volume of rectangular prism=B*H
B=area of the base> 5*3> 15 units ²
H=3 units
Volume of rectangular prism=15*3> 45 units³
and 
Volume of rectangular prism=L*W*H
Volume of rectangular prism=5*3*3> 45 units³

the answer Part 3) is the option
C) V=LWH 

Part 4) Part 3) we know that
Volume of rectangular prism=B*H
B=area of the base> 5*5> 25 units ²
H=7 units
Volume of rectangular prism=25*7> 175 units³
and 
Volume of rectangular prism=L*W*H
Volume of rectangular prism=5*5*7> 175 units³

the answer Part 4) is the option
C) V=LWH
