Step-by-step explanation:
let the dimensions be in x
so, dimensions are =
length ( L ) = 4x
breadth ( B ) = 2x
height ( H ) = x
surface area = 2 ×( LB + BH + LH )
1372m² = 2 ×( 4x *2x + 2x *x + x * 4x )
1372m² = 2 ×( 8x + 2x + 4x )
1372m² = 2 ×( 14x)
1372m²÷2 = 14x
686m² = 14x
686m² ÷14 = x
49 = x
so, therefore
