The question is in the diagram, Thank you!

Answer 1

$\huge\pink{\underline{\red H\orange e\purple l\blue l\green o}}$

$\huge\orange{\mid{\overline{\underline{\mathfrak{Solution:-}}}}\mid}$

V1 = 7 ×3×10 = 210 cm^3

V2 = 7×2×10 = 140 cm^3

V3 = 3×3×10 = 90 cm^3

So,

Total Volume = 210+140+90 = 440 cm^3

Hence, Toatal Volume of the solid is 440 cm^3.

Answer 2

Divide the solid into three cuboids

1)The one in the bottom

l=8cm

b=7-4=3cm

b=10cm

Volume =l×b×h

=8×3×10

=240cm^3...........(1)

2)The left one

l=3cm

b=10cm

h=4cm

Volume = l×b×h

=3×4×10

=120cm^3..........(2)

3) The right one

l=2cm

b=10cm

h=4cm

Volume=l×b×h

=2×4×10

=80cm^3..........(3)

Add the volumes in (1), (2), (3)

240 cm^3+120cm^3 + 80cm^3

=440cm^3

Therefore the volume of the solid id 440cm^3
