Question

25 points! Find the volume of a cuboid: Length Breadth Height 1. 7cm 3cm 6cm 2. 15m 9m 10 m 3. 25mm 12mm 15mm

Answer 1

Answer:

`1)   126CM³

2) 1350M³

3)    4500MM³

Step-by-step explanation:

1)  VOL. OF CUBOID=LBH

L=7CM

B=3CM

H=6CM

VOL.=7x3x6

=126CM³

2) L=15M

B=9M

H=10M

VOL.=15x10x9

=1350m³

3)     L=25mm

        B=12mm

       H=15mm

VOL. = 25x12x15

=4500mm³

thank you!!! please make it the brainliest !! if you like

Answer 2

Hiii!!!

here's ur answer...

given:-

length of the cuboid = 15m

breadth of the cuboid = 6m

height of the cuboid = 5dm

we know that 10dm = 1m

therefore 5dm = 5/10

= 0.5m

→ volume of the cuboid = l×b×h

= 15×6×0.5

= 45m³

→ CSA of the cuboid = 2h(l+b)

= 2×0.5(15+6)

= 1×21

= 21m²

→ TSA of the cuboid = 2(lb+bh+lh)

= 2[(15×6)+(6×0.5)+(15×0.5)]

= 2(90+3+7.5)

= 2×100.5

= 201m²

hope this helps...!
