Question

a cornflakes box measures 30 cm by 24 cm by 8 cm . calculate the surface area of the box​

Answer 1

Answer:

l = 30cm

b = 24cm

h = 8cm

surface area = 2 (lb + bh + hl)

2 ( 30 × 24 + 24 × 8 + 8× 30)

2 ( 720 + 192 + 240)

2 × 11 5 2

2304 cm²

Answer 2

Dear Student,

◆ Answer -

Surface area of the box​ = 2304 m^2

● Explaination -

# Given -

l = 30 cm

b = 24 cm

h = 8 cm

# Solution -

Surface area of the box is given by formula -

TSA = 2 (lb + bh + lh)

TSA = 2 (30×24 + 24×8 + 30×8)

TSA = 2 (720 + 192 + 240)

TSA = 2304 m^2

Hence, the surface area of the box​ is 2304 sq.m.

Best luck dear..
