Question

Find the volume and total surface area of a cuboid with length =6m, breadth=4.8m and height =80cm?

Answer 1

2 into lb + bh + HL is the formula of volume of cuboid
2 (6 into 48 by 10 + 48 by 10 into 80 + 80 into 6)
2 (28.8 + 384 + 480)
2(892.8)
1785.6 is the TSA of cuboid

and the formula of volume of cuboid is l into b into h
6*4.8*80
2304 is the volume of cuboid

Answer 2

Volume of cuboid = length × breadth× height

Surface area of cuboid = 2[(length× breadth) + (breadth ×height) + (height× length)

________________________________________________


Volume of cuboid = 600×480× 80 
                               = 288000 × 80
                               = 23040000 cm³


Surface area = 2[ (600× 480) + (480 ×80)+ (80 × 600)]

Surface area = 2[ 288000 + 38400 + 48000]
                       = 2[374400]
                       =  748800 cm²




i hope this will help you
