Question

answer the above two question

Answer 1

Answer:

Step-by-step explanation:

⏩ Let the dimensions of cuboid be 4x, 2x, 1x

TSA of cuboid = 2(lb + bh + hl)

=> 2800m^2 = 2( 4x*2x+2x*1x+1x*4x)

=> 2800 = 2(8x^2 + 2x^2 + 4x^2)

=> 2800 = 2(14x^2)

=> 2800/2 = 14x^2

=> 1400 = 14x^2

=> 1400/14 = x^2

=> 100 = x^2

=> 10 = x

Therefore dimensions = 4x = 4*10=40

=> 2x = 2 * 10 = 20m

=> 1x = 1 * 10 = 10m

▶ Volume = l * b * h

=> 40 * 20 * 10

=> 8000 m^3
