A rectangular solid measures 4.9 m by 8.3 cm by 6.8 dm. Express its volume in cubic meters, liters, cubic inches, and cubic feet

Igoryamba

Answer:

Part 1) The volume is 0.276556 m³

Part 2) The volume is 276.556 l

Part 3) The volume is 16,886.94 in³

Part 4) The volume is 9.68 ft³

Step-by-step explanation:

A rectangular solid measures 4.9 m by 8.3 cm by 6.8 dm

Part 1) Express its volume in cubic meters

Convert the measures to meters

Remember that

1 m=100 cm

1 m=10 dm

4.9 m

8.3 cm=8.3/100=0.083 m

6.8 dm=6.8/10=0.68 m

Find the volume

V=4.9*0.083*0.68=0.276556 m³

Part 2) Express its volume in liters

Convert the measures to liters

Remember that

1 m³=1,000 l

we have

V=0.276556 m³

Convert to liters

0.276556 m³=0.276556*1,000=276.556 l

Part 3) Express its volume in cubic inches

Convert the measures to inches

we have

4.9 m, 0.083 m, 0.68 m

Remember that

1 m= 39.3701 in

4.9 m=4.9*39.3701=192.91 in

0.083 m=0.083*39.3701=3.27 in

0.68 m=0.68*39.3701=26.77 in

Find the volume

V=192.91*3.27*26.77=16,886.94 in³

Part 4) Express its volume in cubic feet

Convert the measures to feet

we have

4.9 m, 0.083 m, 0.68 m

Remember that

1 m=3.28084 ft

4.9 m=4.9*3.28084=16.08 ft

0.083 m=0.083*3.28084=0.27 ft

0.68 m=0.68*3.28084=2.23 ft

Find the volume

V=16.08*0.27*2.23=9.68 ft³
