Question

please answer this question ....​

Answer 1

Answer:

volume of wood =volume of cuboid -6*volume of hemisphere

volume of cuboid

length=22.5

breath =15

height =6

volume of cuboid =lbh

22.5*15*6

2025

volume of hemisphere

r=2cm

=(2/3)Πr^3

=(2/3)*22/7*2^3

=2/3*22/7*8

=2/3*176/7

=352/21

=16.76

now volume of wood =volume of cuboid -6*volume of hemisphere

2025-100.56

1924.44

Answer 2

total volume of wood=dimensions if cubiod -hemispherical cavities

volume if hemisphere=2/3π r^3

=22.5×15×6-6×2/3πr^3

135×15-4×22×8×1/7

solving this u will get ur required answer
