Question

the outer dimensions of a wooden box are 50cm 45cm 33cm. the thickness of the box is 1.5cm. if the wood weight is 0.8gms per cubic centimeter. Find the weight of the box?

Answer 1

Step-by-step explanation:

if the box is solid then the volume be 50×45×33= 74250cm3

then we have to remove the volume of void part.. so 1.5 cm is deducted from all of this

50-1.5=48.5

45-1.5= 43.5

33?-1.5=31.5

now the volume of the void part is 48.5×43.5×31.5= 66457.125cm3

hence only volume of the wood be (74250-66457.125)cm =7792.875cm3

for 1cm3 wood weight is o.8gm

then for 7792.875cm3 wood weight be= 6234.3gm = 6.2kg
